    repairing a car for a mate whos had trouble starting his a2 for many months from cold .one running its fine , it seems to be down to fuel run back .
    its the older one with no inline fuel pump , so we fitted one with a timed circuit to prime the fuel system first , this seemed to eliminate the starting problem , but has know causes another problem , after the car has warmed up it starts to cut out and seems to be lack of fuel to the tandem pump.
    . i seem to think that the fuel piping is incorrectly connected from the fuel filter as the return fuel cooler seems to go to the fuel feed not return . i also need to know what the valave is on the drivers side just in front of the rear wheel as there are 4 fuel lines going into this .
    this seems to be the only model hat has such a wierd complex setup . all the other vw have an inlank pump that feeds the tandem ,then a simple return line through the diesel cooler back to the tank .

    never seen so many fuel lines on one vehicle going to and fro from the tank
