Sorry, I got 'into it' and forgot to take pictures.

I just connected high pressure fuel hose from the pump directly to the metal hat. I also drilled two 5/16" holes in the bottom of the basket thinking this would prevent fuel pump starvation. Was it required? Not completely sure, but my fuel flows very well.

wouldnt that bypass the fuel pressure reg by going straight to the hat?
if not then where is the fuel pressure reg? here is a pic int he first post of the link that has a return going back into the bucket. did you bypass that too?? or is the sender differnet?

The fuel pressure regulator is on the end of the fuel rail and yes, I bypassed the return into the bucket as well.

watman02 · 02-05-2013, 12:14 PM

Do you have a return style system? or ru referring to the fuel Psi sensor?

fastlane · 02-05-2013, 03:58 PM

The regulator on the end of the fuel rail works in conjunction with the FPDM to pulse the fuel pump in order to maintain a certain pressure level. That isn't being bypassed. There is a return line directly off the pump on top of the bucket lid in the tank. That is being bypassed.

I am running a returnless system.

Yellow wire coming off fuel hat into tank?
I looked at a wiring scematic and it's not even listed?
When I fill the tank now, the gauge does not read and the low fuel light stays on. The fuel leveler does not seem to be caught on anything.

The yellow wire is the fuel level sensor signal wire. That has to be connected. There is a white wire that screws to the bottom of the fuel level sender as well. That is the ground wire. Make sure both are connected well.
