Default Need help re-plumbing fuel system

Since installing new fuel tanks I have not been able to get more than 4500 rpm. Before the switch WOT was 5300 rpm.

Tonight I took off the fuel pick ups and they are very small! So I am thinking the motors are being starved of fuel. The motors are supercharged, and the fuel pressure regulator has a fitting to return unused fuel back to the tank, via the fuel cooler. The return fitting also has a pick up tube attached. I was thinking I could Tee these 2 together to increase fuel flow, and run the return line up to the front of the tanks and Tee into the vent line.

Will this work? Is there another way?

Thanks

Yes there is and yes you are starving the motors from what you're explaining here. PM me a number so we can talk and I will help you out.

Hey Ken, sorry to hear of your fuel line hassles.

Hey guys what is happening Sunday? Am I invited?

I likely will not be driving my boat, but if I can do the pavement thing, I am up for any festivities.

You folks can email the info to:

[email protected]

Thanks,

Chris
