External Fuel Pump Replacement

Post by Imatk » Fri Jun 12, 2020 11:24 pm

Trying to find a writeup or some information on how to replace the external fuel pump.

Following the Bentley it reads "Remove insulated holder from bracket."

Yeah how the heck do you do that?

Also how do you manage to replace the fuel expansion tank that's way up on the side of the fuel tank? Do you have to drop the fuel tank?

It's a pain if everything if everything is rusty as mine was so start soaking the bolts and nuts in penetrating oil..

From memory, remove the 3 nuts that hold the fuel pump cage to the car, remove the electrical connections, clamp the fuel hose going into the fuel pump but depends on how much fuel in in your tank? undo the fuel lines going in and out of the pump then remove the the whole unit, take the foam out of the cage and you should get to the fuel pump.

I had a nightmare undoing the fuel lines into the pump as you need a thin spanner to hold the pump still while you undo the connections and mine did not want to come undone and you can't use any heat for obvious reasons..

Quick search for Mk1 golf as Cabriolet has the same set up, lots of threads out there.

Can't help much with the swirl pot as not done that but I guess you will need to drop the tank a bit to gain access?
