I have the same or similar EFI system FiTech. It worked fine for bout a day then started doing what urs was doing. The system was brand new from Summit. As u can see in photo to left went on my SS. Turns out the pump was bad wouldn't hold pressure ran like crap. So contacted Summit they sent me a new pump for the EFI runs great that maybe ur problem as well. Just a thought. I have no regulator or pressure gauge FYI I hear it & the vac pump come on each pump up & that's it no more noise.
Thanks for the input. It's always nice when someone else has the same issue as me lol.
I have a fuel pressure gauge on the feed port of the throttle body and it reads between 35-40 psi at idle. It's been like that since I got it running. The bouncing is due to the radical idle but it still seems too low since the system supposedly needs 58psi.
When I messed with it yesterday it seemed like the issue came out a lot sooner. I changed thermostats so after I let it warm up, pop the T-stat and topped it off with coolant I took it for a spin and the problem was there right away so it appears to be getting worse. I pulled apart my fuel filters to find the pre filter containing quite a bit of metal shavings. I would assume from when I drilled the tank for the sump. I must have missed a bunch of debris. My bad. Maybe some got through the filter and killed the pump?
I still am not having any luck getting a hold of FiTech. Tried calling 3 different tech's, email, facebook message, and a facebook post on their wall asking if they even had anyone working there anymore. Im getting pissed off that I haven't been able to talk to anyone in over a week.
