This hose is listed in Porsche parts catalogues for selected Porsche 911 SC, 930 Turbo and 944 applications, where it connects components of the fuel tank ventilation or activated charcoal canister system.
The fuel tank ventilation system manages the movement of air and petrol vapour as fuel is consumed and temperature changes affect pressure inside the tank.
The hose provides a flexible passage between the specified ventilation components, helping maintain the intended vapour routing and allowing the fuel tank to breathe through its designed ventilation circuit.
Manufactured to Porsche's original equipment specification, the hose has nominal dimensions of 12 × 2.5 mm, corresponding to a 12 mm internal diameter and 2.5 mm wall thickness.
The hose is intended to be cut to the correct length for its particular installation, where supplied as bulk hose.
During normal operation, fuel tank ventilation hoses are exposed to petrol vapour, changing temperatures and vehicle vibration. These conditions can gradually affect the flexibility and condition of the hose material.
Over time, an ageing hose may become brittle, cracked, split, swollen or loose at its connection points.
A damaged hose can allow petrol vapours to escape or interfere with the proper operation of the ventilation circuit. This may produce a persistent fuel smell, particularly after refuelling or when the vehicle is parked in warm conditions.
Replacing a defective hose with a Genuine Porsche component helps restore the intended fuel vapour connections, reduce unwanted vapour leakage and maintain the original ventilation arrangement.
Ideal for classic Porsche fuel system repairs, tank ventilation maintenance and restoration projects, this Genuine Porsche Hose provides a correctly specified replacement for compatible applications.
What This Product Does:
The hose forms part of the vehicle's fuel tank ventilation or fuel vapour management circuit.
Its primary function is to provide a flexible passage for air and petrol vapour between designated components.
As the engine consumes fuel, the volume of liquid within the tank decreases. The ventilation system allows the resulting changes in tank pressure to be managed.
Changes in ambient temperature also affect fuel vapour pressure. The tank ventilation arrangement accommodates these changes through its connecting hoses, expansion chambers and other components.
In vehicles fitted with an activated charcoal canister, fuel vapours are routed through the appropriate vapour management system rather than being released freely.
The hose supports these functions by maintaining the intended connection.
Its main functions include:
- Supporting fuel tank ventilation: Provides a passage for air and fuel vapour within the designated circuit.
- Helping manage tank pressure: Supports normal pressure equalisation as fuel volume and temperature change.
- Connecting ventilation components: Links the relevant expansion chambers, pipes, fittings or charcoal canister components.
- Maintaining vapour routing: Helps keep fuel vapour within the intended ventilation pathway.
- Reducing unwanted vapour escape: Maintains a secure connection when correctly installed.
- Accommodating vehicle movement: Provides flexibility between connected components.
- Maintaining unrestricted flow: Allows air and vapour to pass through the specified hose section.
- Supporting emissions equipment: Helps preserve the original vapour management arrangement on vehicles equipped with an activated charcoal canister.
- Maintaining factory hose routing: Restores the correct hose size and installation arrangement.
- Supporting fuel system reliability: Helps prevent faults associated with cracked, collapsed or disconnected ventilation hoses.
Symptoms Of Wear Or Failure:
Ageing fuel tank ventilation hoses can deteriorate through prolonged exposure to petrol vapour, heat, vibration and repeated changes in temperature.
Common symptoms and signs of a worn or damaged hose include:
- Petrol smell around the vehicle: Escaping vapours may create a noticeable fuel odour.
- Fuel smell after refuelling: Vapour leakage may become more noticeable when the tank is full.
- Fuel smell in warm weather: Increased vapour formation may expose weaknesses in the ventilation circuit.
- Visible cracking: The hose surface may develop cracks as the material ages.
- Hardened or brittle hose: Loss of flexibility can affect sealing around the connection fittings.
- Split hose ends: Cracking near connection points may allow vapour leakage.
- Loose hose connections: Deteriorated hose ends may no longer grip fittings securely.
- Disconnected hose: An insecure connection can leave part of the vapour circuit open.
- Swollen or distorted material: Ageing or chemical incompatibility may affect the hose shape.
- Collapsed hose sections: Deformation may restrict airflow through the ventilation circuit.
- Kinked hose routing: Incorrect installation can obstruct the intended ventilation passage.
- Visible abrasion: Contact with sharp edges or neighbouring components may wear through the hose.
- Unusual fuel tank pressure symptoms: A restricted ventilation system may contribute to excessive pressure or vacuum in the tank.
- Damaged hose clamps: Loose or corroded clamps may compromise secure attachment.
- Persistent vapour odours after servicing: Incorrect routing or inadequate sealing may leave a connection leaking.
Why Replacement Matters:
Replacing a deteriorated ventilation hose helps maintain the correct operation of the fuel tank breathing and vapour management system.
An old hose may become cracked or brittle, allowing fuel vapours to escape around its surface or connection points.
A collapsed or incorrectly routed hose may also restrict the normal movement of air and vapour through the system.
Installing a Genuine Porsche replacement Hose 99918107240 helps to:
- Restore the intended ventilation connection: Replace a defective section of hose.
- Reduce petrol vapour leakage: Address unwanted fuel odours caused by a confirmed hose defect.
- Maintain fuel tank breathing: Support the intended movement of air and vapour.
- Help prevent ventilation restrictions: Replace collapsed or obstructed hose sections.
- Restore secure hose attachment: Renew hardened or split hose ends.
- Preserve original hose dimensions: Use the specified 12 × 2.5 mm hose reference.
- Maintain factory hose routing: Cut and fit the correct length for the relevant application.
- Support vapour management components: Maintain connections to expansion chambers or activated charcoal canisters.
- Reduce further deterioration: Replace ageing hose material before complete failure.
- Support fuel system refurbishment: Renew old hoses during fuel tank or emissions system servicing.
- Preserve classic Porsche originality: Maintain the factory-style ventilation system.
- Provide Genuine Porsche quality: Use an original equipment hose reference for the specified application.
Replacement is recommended when the hose shows cracks, brittleness, swelling, damage, persistent vapour leakage or an insecure fit.
The surrounding clamps, connection fittings, expansion chambers and other ventilation hoses should also be inspected.

Also described as a fuel tank breather hose, this component forms part of the vehicle's fuel tank ventilation system, allowing air and fuel vapours to move through the designated ventilation circuit.
The fuel tank ventilation system is essential for managing pressure changes within the fuel tank as fuel is consumed, temperatures change and petrol vapour develops.
Rather than allowing fuel vapours to escape through uncontrolled openings, the ventilation arrangement routes them through the appropriate hoses, expansion chambers and associated components.
The Genuine Porsche Vent Hose provides a flexible connection within this system, helping maintain the intended flow of air and fuel vapour.
The hose is associated with the fuel tank ventilation assemblies used on selected Porsche 911 SC and 930 Turbo vehicles.
During normal operation, the fuel level changes as the engine consumes petrol. At the same time, variations in ambient temperature can cause fuel vapour to expand or contract.
The ventilation system accommodates these changes, helping prevent excessive pressure or vacuum from developing within the fuel tank.
A correctly installed breather hose helps maintain the integrity of the ventilation circuit and reduces the risk of vapour escaping through damaged connections.
Over time, the original hose may deteriorate because of age, fuel vapour exposure, heat, vibration or repeated movement.
The material can become hardened, brittle, cracked or split, while the ends may lose their ability to form a reliable connection with the associated fittings.
A damaged vent hose can allow petrol vapours to escape, producing an unpleasant fuel smell around the vehicle. Depending on the location and nature of the damage, it may also affect the operation of the tank ventilation system.
Replacing a worn or damaged hose with a Genuine Porsche component helps restore the original ventilation arrangement, maintain secure vapour connections and support reliable fuel tank pressure management.
Ideal for classic Porsche fuel system maintenance, tank ventilation repairs and restoration projects, this Genuine Porsche Vent Hose provides a factory-specified replacement for compatible applications.
What This Product Does:
The vent hose is part of the fuel tank breathing and vapour management system.
Its primary function is to provide a passage through which air and petrol vapours can move between the designated components of the fuel tank ventilation circuit.
As fuel is consumed, air must be able to enter or move through the ventilation arrangement to prevent excessive vacuum developing inside the tank.
When fuel temperature rises, petrol vapour can expand and increase pressure inside the tank.
The ventilation system accommodates these pressure changes through its associated hoses, expansion tanks and vapour management components.
The vent hose supports this process by maintaining the required connection within the system.
Its main functions include:
- Allowing fuel tank ventilation: Provides a passage for air and fuel vapour within the specified ventilation circuit.
- Supporting pressure equalisation: Helps prevent excessive pressure differences from developing in the fuel tank.
- Accommodating fuel vapour expansion: Allows vapour movement as temperature and fuel conditions change.
- Supporting fuel tank breathing: Helps maintain the intended ventilation arrangement as petrol is consumed.
- Connecting ventilation components: Provides a flexible connection between associated pipes, fittings or expansion chambers.
- Limiting unwanted vapour escape: Helps contain fuel vapours within the designated ventilation pathway.
- Maintaining correct system routing: Preserves the factory-designed arrangement of ventilation hoses.
- Supporting reliable fuel tank operation: Helps prevent ventilation restrictions caused by a damaged or collapsed hose.
- Accommodating normal vehicle movement: Provides flexibility between connected components.
- Supporting fuel system maintenance: Allows deteriorated sections of the ventilation circuit to be renewed.
The vent hose does not pump fuel or deliver pressurised petrol to the engine.
It is a fuel tank ventilation component, separate from the main fuel supply and return hoses.
Symptoms Of Wear Or Failure:
Fuel tank ventilation hoses are exposed to petrol vapour, temperature changes and long periods of service.
On older Porsche vehicles, ageing rubber and deteriorated hose connections can cause ventilation faults.
Common signs and symptoms of a worn or damaged vent hose include:
- Petrol smell around the vehicle: Escaping fuel vapour may produce a noticeable petrol odour.
- Fuel smell in the luggage compartment: A leaking ventilation hose in the front luggage compartment area may allow vapours to accumulate.
- Fuel smell after refuelling: Vapour leakage may become more noticeable when the fuel tank is full.
- Fuel smell during warm weather: Higher temperatures can increase vapour generation and expose weaknesses in the ventilation circuit.
- Cracked hose material: Ageing may cause visible splits or cracks in the hose surface.
- Hardened or brittle hose: Rubber deterioration can reduce flexibility and sealing performance.
- Loose hose connections: Worn hose ends may no longer grip the connecting fittings securely.
- Split hose ends: Repeated removal or prolonged ageing may cause cracking around the connection points.
- Collapsed hose sections: Deformation may restrict the intended movement of air or vapour.
- Blocked ventilation passage: Debris, deterioration or incorrect hose routing may obstruct the circuit.
- Excessive pressure release when opening the fuel cap: Abnormal tank pressure may indicate a ventilation restriction.
- Fuel tank vacuum symptoms: A severely restricted ventilation system may interfere with normal fuel tank breathing.
- Visible hose swelling: Chemical exposure or incompatible hose materials may affect the hose's shape.
- Disconnected ventilation hose: A detached hose may leave the circuit open to the surrounding area.
- Deteriorated hose clamps: Corroded or loose retaining components may compromise the connection.
- Repeated fuel vapour odours after repairs: An incorrectly routed or inadequately secured hose may continue to leak vapour.
Why Replacement Matters:
Replacing a deteriorated fuel tank vent hose is important for maintaining the original fuel tank ventilation arrangement.
A cracked or split hose may allow petrol vapours to escape into areas where they should not be present.
A collapsed or obstructed hose may also interfere with the fuel tank's ability to manage normal pressure changes.
On classic Porsche vehicles, original rubber components may have experienced several decades of heat exposure, vibration and contact with fuel vapours.
Even where a hose appears intact, its ends may have hardened and become less effective at sealing against the connecting fittings.
Installing a Genuine Porsche replacement Vent Hose helps to:
- Restore fuel tank ventilation: Renew a damaged connection within the breathing system.
- Reduce unwanted petrol odours: Address vapour leakage caused by a confirmed defective hose.
- Support pressure equalisation: Maintain the intended movement of air and fuel vapour.
- Prevent unwanted vapour escape: Restore the appropriate connection between ventilation components.
- Replace deteriorated rubber: Renew cracked, brittle or hardened hose material.
- Maintain secure hose connections: Restore proper attachment to the associated fittings.
- Prevent ventilation restrictions: Replace collapsed or obstructed hose sections.
- Support fuel tank operation: Maintain the correct breathing arrangement during normal fuel consumption.
- Preserve factory hose routing: Restore Porsche's intended ventilation layout.
- Support fuel system refurbishment: Replace ageing components during tank or expansion chamber servicing.
- Improve long-term reliability: Reduce the likelihood of further hose deterioration.
- Support classic Porsche restoration: Maintain the original fuel tank ventilation system.
- Maintain Genuine Porsche specifications: Use the specified original equipment reference rather than an unverified generic hose.
Replacement is particularly recommended when the hose is visibly cracked, hardened, split, swollen, detached or otherwise damaged.
The surrounding ventilation hoses, expansion tanks, fittings and retaining clamps should also be inspected during replacement.
