Hi all, I have dual walbro in tank pumps, racetronix hotwire kit, boost activated hobs switch, -8 feed, fuel reg to fuel rails with 95lb injectors. I'm noticing that now when I turn the ignition to on (not started) my fuel pressure goes to 50psi like normal, but now slowly drops down to 20-25psi after 10ish seconds. Car can be hard to start as you could imagine. Once started pressure is good. The car was just tuned for e85 and went through and replaced the fuel filter. The only other changes were the injectors from 60lb to 95lbers.

What are some common things I can test to see if its an issue? Tomorrow I'm going to try and switch the hotwire kit on the pumps to see if I can isolate it to the pump. I'm wondering if the e85 could be causeing the issue. I already replaced the filter because of irragular gas delivery that seemed to clear up after the swap.

Thanks
-Will

Could be a leaking injecor, a leak in the pump fuel hose, or the regulator.

Pull the rails first as it is easy, cycle the key & see if an injector drips.

Thanks Lonnie, I'll give that a shot tomorrow. Any other tests if it comes back that those injectors aren't dripping?

It's also worth noting that the 95lb injectors are an ls2 style and I have wire harness adapters. Not sure if that helps at all.
