Alright, hopefully a relatively simple issue. I’ve got a 95 gmc with a lq9 and some bolt ons, 706 heads, and Texas speed cam. For the fueling it has a quantum 255 in the stock sending unit, -6an lines to a c5 vette filter/regulator, and 50 lb injectors. I’ll be doing a pull and I’ll hit around 5k rpm and fuel pressure will be around 32 psi. It’s 55psi at idle. I am suspecting that it’s either the stock sending unit or the regulator/filter. Any ideas?
