Anyone here ever changed the fuel pump in their B5? The pump output has a Y pipe on it, one arm of the Y goes via the check valve to the feed outlet, where does the other arm go? I have a spare spigot on the return piping in the tank but this seems counter intuitive, why route the pump output back to the return pipe?
I have tried it plugged in there and the car doesn’t run.
The new pump runs fine on the bench.
The old one needed a bang with a mallet to start up and then ran slow and noisy.
FP Relay works
11.8 volt at the fuse when cranking.
Wondering if I’ve got the pipes in the tank mixed up!
Wish I’d taken more pics!
