I want to make sure the fuel pump is working properly, but I'm not sure how to check the fuel pressure. Can anyone provide instructions on how to do this for an Audi 80?
ReplyYou will need a fuel pressure gauge to check the pressure. First, locate the fuel pressure test port on the fuel rail. Then, attach the gauge and turn on the ignition. The gauge should read between 30-35 psi. If it is below this range, it may indicate an issue with the fuel pump or fuel filter.
Before checking the fuel pressure, make sure the fuel pump is properly connected and functioning. If the fuel pump is faulty, it may affect the pressure reading. You can also refer to the Audi 80 manual for specific instructions on how to check the fuel pressure.
