Fuel Tank Sender Unit

Ensure accurate fuel readings and dependable performance with fuel tank level sender units from Design911. These precision-engineered components provide real-time data to your Porsche’s fuel gauge, helping you monitor tank levels and avoid unexpected empty readings.

What They Are & What They Do
A fuel tank level sender unit is an electrical sensor located inside the fuel tank. It uses a float and variable resistor to measure the amount of fuel remaining and send this data to the instrument cluster or fuel gauge.
In modern Porsche models, the sender works with digital sensors and the vehicle’s ECU, providing highly accurate readings and supporting fuel management systems.

Why They Fail
Over time, sender units can fail due to fuel contamination, corrosion, worn electrical contacts, or damaged floats. Ethanol-blended fuels, debris, or moisture can also cause resistance inaccuracies, leading to fluctuating, stuck, or incorrect fuel gauge readings.
Common symptoms include a gauge that reads empty when the tank isn’t, fluctuating levels, or non-functional gauges.

Why They Should Be Replaced
Replacing a faulty sender unit restores accurate fuel readings, prevents running dry, and ensures proper fuel system operation. A new sender also helps maintain instrument accuracy and electrical reliability.
Design911 offers a wide selection of genuine Porsche and high-quality aftermarket fuel sender units, designed for exact fitment, precision measurement, and long-lasting durability. Whether restoring a classic 911 or maintaining a Cayman, Boxster, or Taycan, we have the perfect unit for your Porsche.
