I have a 1989 Silverado with a remanufactured tbi, new injectors, new Russell performance stainless line, an6 fittings, new ac delco fuel pump, new fuel tank and I'm only getting 6 psi at my Tbi. I have an adjustable fuel pressure regulator and new diaphragm and spring. When I kink the return line it jumps to 14psi. No kinks in the lines. Please help.
