My H/C '99 has a stock fuel pump and '98 injectors. I'm installing a TNT F1 wet kit, and will probably stick to 100hp jets max.

What should the FPSS be set at?

 

If you don't have any other mods like head ,cam combinationthe stock fuel pressure should be fine 58psi at idle and about 53 to 55psi at wot the tnt kits I beleive are set for 50psi so it will run real safe and I have heard of people runing like 1200 psi bottle pressure to lean it out a little and it will pick up in et but I have never done this myself I have a nx 2 stage kit that I haven't ran yet Hopefully soon though.

I am an idiot I see now that you are using a fuel press. safty switch I would set it at like 50psi if it drops a little below for a second it would be ok but with out a gauge you don't know how low it drops. So 50psi will be safe if it is shuting off then lower it a couple pounds and if it don'y shut off ok but if it does there is a problem and you need to check fuel pressure
