Frequently Asked Questions

Typically, the fuel pump is located in the fuel tank, although the exact location can vary depending on the make and model of the vehicle. For example most older car used manual fuel pump that located beside the engine cylinder while some car like Mercedes Benz fuel pump located under the car body and other car like Golf 3 have two fuel pump one was located under the car body and the other one was mounted inside the fuel tank. The fuel pump is a crucial component in a vehicle’s fuel system, responsible for delivering fuel from the gas tank to the engine.

The fuel pump is one of the simplest and most rugged parts of the fuel system. They are usually built to last and are tough because they are located in a hard-to-reach place in your fuel tank. In most cases, you can expect your fuel pump to last about 100,000 miles before it needs to be replaced, but most people never need to replace their fuel pumps. Fuel pumps have been known to last over 200,000 miles in some cases. However, this number can change depending on the circumstances and conditions you drive in.

Step 1: Without starting the engine, turn the key to the "Run" position and listen for a buzzing sound from the fuel pump. If you can hear it, this indicates that it is turning on.

Step 2: Disconnect the electrical connector. If the pump does not turn on, remove the electrical connector on the pump, connect the fuel pump circuit with special wiring, turn on the ignition switch, and the engine will not start. If the fuel pump works, it means there is no problem with the pump.

Step 3: Check fuel pressure. Start the car and let it idle. Install a fuel pressure gauge, run the pump, and note the pressure reading. Make sure the pressure is correct. The fuel pump may be defective if it does not reach the required pressure. Between 30 and 80 PSI is required for a typical port-injected vehicle.

Step 4: Test fuel delivery. Use a special gauge (such as a beaker) to measure if the oil pump's oil delivery and oil return are normal.
