Hi All,

I just registered a 7psi of fuel line pressure for my EFI system. It took a couple of hours to get the gauge in-line and once I fired up the engine, I at first thought I had no pressure.

I spoke with Gil earlier and he told me it should be between 33-43 psi. I revved up the motor and initially, the pressure dropped to around 3.5psi and then as I'm holding the revs up a bit, the pressure returned to 7psi. Never any higher.

It seems like I need a new fuel pump. But my I can't seem to make any sense of the fact that as I open the throttle, my fuel pressure actually goes down. Why is that? Or is this just another indication that my fuel pump is bad?

I've done a search on this subject and didn't find anything relevant. But I did find a lot of discussion on surge tanks. I have experienced fuel starvation numerous times and would be interested in knowing if there is an off the shelf tank that someone here has found that works well on our GTs. I'm going to do a search on readily available surge tanks and hope to find something that can just work.

Thanks for any info you might provide,

Manny
