Gq mechanical fuel pump

[Pezzer]

Can anyone explain which hose goes where or is the a diagram showing fuel flow?

There should be an arrow on the pump itself showing flow directions one pipe comes from the tank and then the other leads to fuelfilter and carby

The large diameter I think must be feed from tank, there are 2 others 1 must be to filter and carby and the other a return to tank it's which way round these 2 go?

I really don't think it would matter as if its returning it to the tank it would be the same flow I would suggest get someone the crank the car over and see which one pumps out then that's the one to the carby

Hi,

From my experience, there isn't a return on carby motor?
Bottom pipe is to filter/carb, top one is from tank (both same size) and third one should be easy :)

There is s return on mine. Its before the carby though. Theres a valve bolted to my intake manifold. A certain pressure goes up to the carby. The rest is sent back to the tank.
Theres three lines. Feed to filter and carby, return line to the tank and the third is a vapour line.
Dont know which is which though
