I've replaced the transfer pump in the tank....and now find that i need to replace the main fuel pump that i believe is located in the passenger side rear wheel well. Do I need to remove the rear wheel to get at the pump? Also....I'd like any advice you may about how to remove and replace the old pump.

Hi I had a look at your pic and never show one of those pumps in a vw before I think the only place to get it is at a place that sells after market parts,take it to a shop and mach it up with what they have.
On a Digifant fuel system, the fuel pump is mounted in a reservoir
under the rear of the vehicle. The fuel filter is also in this area.
The reservoir holds one liter of fuel and is supplied by a small
transfer pump in the tank. The transfer pump can be replaced separately
even though they are installed and removed as a unit.
Motronic system uses two fuel pumps. The first is a small transfer pump
to get the fuel out of the tank and the second boosts the fuel pressure
to the necessary amount. The transfer pump is located inside the tank
and the main pressure pump can be found under the vehicle. This
transfer pump is located under the rear seat and is part of the fuel
gauge sending unit. The main fuel pump can be found in the reservoir in
front of the rear axle beam. There is a check valve inside this pump to
maintain pressure in the lines, especially on hot days, to avoid vapor
lock. The fuel filter is mounted to the side of the reservoir. This
filter has no specified replacement interval and should be good for the
entire service life of the vehicle. Whenever the ignition key is in the
on position, the pump should run for at least two (2) seconds to
pressurize the fuel lines. If the Engine Control Unit (ECM) does not
see a signal from the Hall Effect sensor in the distributor it will
shut the pump off. If a Hall Effect signal is present, the pump will
continue to run as long as a signal is detected. It is this Hall Effect
signal that signals the ECM that the engine is rotating therefore
indicating that fuel is needed. The pump is operated via a relay that
is controlled by the ECM. This relay is located in the vehicles fuse
panel. The main contacts of the relay can be jumped to run the pump
If it's a 2.0L or 1.8l, you'll have to take off the timing belt. I'd suggest looking for a procedure on removing the timing belt and the water pump is under the distributor gear usually. Do NOT loose your marks, or else you can ruin the engine.
Thanks for your replay ! I have not been able to get any fuel coming into the Filter ! so I am thinking that problem is the Fuel Pump and I have not been able to find it's location ! I guess it's in the fuel tank and because it's Sunday I can not even find the part ( Fuel pump) ! If you can tell me where it is that will be great,thanks.Hamid
