Re: Fuel pump replacement instructions

Didn't you need to remove the gas filler and such? It was the most difficult part for me. I even didn't try to remove the pump without pulling the tank out from the car... But it is good to know it is do-able without removing it from the car.

One thing I did to empty the gas tank was to install a piece of wire instead of the relay (so that it would keep running while the key is ON) and disconnect the fuel line at the fuel filter and catch gas there. Obviously, it will not work when the pump is completely dead...

Did you check the fuel pressure when you disconnect the vacuum line to it and it was 35 psi? I believe it was a good idea to replace the pump, since it was 12 yrs old, so you will be able to enjoy driving without worrying about the pump failure for long time, but I don't know if it was absolutely needed to replace the pump at this time...

My fuel pressure regulator said its nominal pressure is 42 psi. And it will not develop 42 psi, unless no vacuum is provided. Otherwise it is more like 37 psi or so after changing fuel pump, filter, and FRP...
