Ok, so heres the deal, i dont know what to rely on. I have an autometer Sport comp II eletric fuel press gauge that reads 43 psi at idle, while the gauge on the FPR reads 58!? which one should i go by? if its the 58, then i clearly need to lower it.. heres a drawing of the setup. Injectors are 1000cc.

The return line is larger (-6 or -8 an) then the stock and -4an Feed line. and the stock fpr is gon (system is a 96+) the system works, its just now im working out a tuning issue,

thanx

Trust the mechanical gauge over the electric one.

tips my hat to you* thank you sir!

they still read differnt, i put the sender directly in line, and it reads lower by~15 psi..i lowerd tha FP to 48 psi via the gauge on the FPR.
Yes the vac line is hooked up to the manifold.

I dont have a tester, and the dam senders are like 80!. and its new to, so idk what to do, I lowerd the fp and added fuel via MS accordingly.. idk..

Contact Autometer. They're great about replacing senders and malfunctioning gauges, i've sent a couple in myself.
