Engine/Transmission (1998.5 - 2002) fuel pressure and some questions

[RConner]

I have 14 psi at idle, 12 psi while crusin and it goes down to 7 psi while wide open throttle for a distance. Is this ok?



You can see my sigs, to that I am adding a attitude with juice. Will this set there fuel pressure warning light off?



Has anybody ever switched from a banks box to an edge. If so did they see an improvment?



Can you stack two boxes that tap the wire and add timing?

The numbers are acceptable... a little low on the WOT. If you add more power, you might get into trouble on the WOT numbers. Relocating the factory lift pump and getting rid of the banjo fittings with a Vulcan kit will help the WOT numbers.

I have an areomotive pump that flows 160 gph at 18 to 20 psi. I was considering rigging up my own fuel system with this pump. Is that to much psi for my injection pump? Do I need a pressure regulator?

Ideal pressuer is supposedly 13. 5 plus/minus 2 psi. You would be above ideal but you might get away with it. Some trucks have problems with hot starts with too much pressure. Mine worked fine with extra pressure for a while before the hot start problems started. I now run a relocated factory pump with big fittings and lines.

I am stacking parts to do mine now. I am going with the Wabro pump and a Malory 4307M regulator. I'll let you know how it works out.
