Hi,

My fuel pump seems to prime - when I turn the ignition on it whirrs for a few seconds. But i do not see any fuel in the return line. Does it need to be primed?

There is a gallon in the tank!

Do I suspect that the fuel pump
What other tests can I do?
Thanks

Frank

What setup are you running?

Low pressure pump to swirl pot with seperate high pressure pump? What EFI?

have you got your fuel lines the correct way round?

Hi,

EFI set up
I have a swirl pot in the tank to a high pressure fuel pump.
I have checked the fuel lines are around the correct way round

Thanks

Stuck/Faulty Fuel Pressure Regulator?

Measure the fuel pressure at the rail?

Is the fuel pump below the outlet on the tank, I know the bosch ones really need a gravity feed.
