It shouldn't have to pump for minutes though. I have my ecu to prime for 3 seconds but it generally doesn't need it.

That's not good as it'll blow back Into your manifold

Nah the top adjusting screwy bit had a o ring between the fpr an the washer its managed to get wee bit mangled have bodged it for now to see if that fixes it. Should know tomorrow while your talking the pipe that's removed from the fuel pump to take it out of the tank what did you do with it?

The return to the tank should connect to one of the side ports, and that pipe to the other side port. The jet pump sucks the fuel from the other side of the tank to keep it even.
