How do you remove a fuel pump and test for a 1984 VW Rabbit?

Answer 1

Testing of a fuel pump is normally done with a fuel pressure gauge test kit. However one can get a good idea about the fuel pump with other observations. If the fuel pump makes a loud high pitched electrical whining sound it's starting to go bad. You can also pull the fuel line and put the end of it in a container then run the pump by jumping the relay for 30 seconds and measuring how much fuel came out ( approximately 1.5 liters). One can also remove the pump and bench test it with extra fuel line attached by using jumpers ( a fused one for the positive lead ) and an extra battery. Don't run the pump dry, use a couple of fuel containers and pump fuel from one to the other.

You may have two fuel pumps if you have the 13 gallon tank. If so one is by the passenger side under the car next to the tank. The other is inside your fuel tank.

The fuel pump is accessible from under the rear seat. Start the car and pull the fuel pump fuse and let the car run until it dies to get the fuel out of the system. Disconnect the battery. Pull up the rear seat and take out the screws that hold down the cover. Disconnect the hoses and the electrical connector and remember where they go. Then unbolt the fuel pump carriage and pull it out. Keep rags handy while you do this to clean up spilled fuel.
