We won't have any test and tune day so I hope we can come close with your help.
Here it is.
typical rear engine dragster.
565...blah blah blah.
new 1250 Rupert alky carb.
#12 hose from fuel cell to Aeromotive belt drive pump.
#10 from pump to fuel log.
#10 return from bypass regulator to fuel cell.

Idle pressure with gas is 3.5 and 6.5 wide open.
George wants 9.5 lbs as soon as I can give it to it.
Think the Aeromotive bypass will do that?
Would going to a #8 return help if it doesn't?

Only have two time runs to get the pressure right. Any prior experience with this pump would be great.

Thanks!

Need to know what type regulator you have but most likely there is a spring pressure that increases the fuel pressure. That spring pressure may be increased by screwing it in some or shimmed.

Jok, The way we set the fuel pressure with our similar APD setup is to put someone in the car and set the trans brake and get the rpm up on the 2 step and set it to 9 1/2- 10 psi. Hope this helps. Kevin

I have used the same procedure as the undertaker only I pulled chip out of two step

the areomotive pump and reg combo should get the pressure up fairly quick.its not like some other brands.i think its the best acting regulator out there

set it at 9lbs at 5000 RPM and don't care where it falls at idle.

Thanks guys, that was the plan just wanted to save a wasted step if the lines were too big but 5000RPM should do it.

Good luck at the races!
