Post subject:  fuel problem answered

Thank you for all the help and I will put that on my to do list which is very long!! I got the holley blue pump(110gph@ 14psi) in last Friday so I decided to not go to the drags but to put on the pump. To make a long story short the car still ran out of fuel as I shift into third. I did not know why! As I was working today I came up with something, the regulator the came with the pump is preset at 7 psi. So I was wondering if I take the regulator up to 14psi and only turn the pump on after the boost is up. Then with the 8 lbs that I am running I will have 6psi above boost psi which is about where I want it. IT WORKS!!!!!!!!!!!
so far, I did not get to a straight back road to stop go thru a full run at it but the car pulled thru third getting onto the highway. It's about time. Since the whether here in pa is great (70 wed.) I was going to try to get to the track on Saturday for test and tune. I will let you know if I go!!!!

Andrew,
Get a regulator that has a pressure/vacumm referance port on it. Connect the port to the intake manifold. Then set the regulator at 6 psi,
engine running, and as the boost comes up the fuel pressure will stay at 6 psi above boost.

Andrew/Charlie,

In case you don't know, you can make the std Holley <FONT COLOR="0000ff"> reg rise w/boost. Drill/tap the top
casting [the part w/the adjustment screw] for 1/8" pipe thread and use a nipple. Run a line to a boost source [manifold]. You must fill the little breather notch in the cover flange [epoxy works well].
This will cause fp to rise with boost.
