In the middle of my lm7 swap. Doing a Calif. emmissions install. Anyway my truck is a 95, and installed a 98 fuel pump assembly, due to that I need the fuel tank press. sensor. Now the fuel gauge is way off. Shows 1/2 tank when its actually empty. Shows extremely full when its full. I adjusted the needle, but that didn't help. I'm thinking about finding a 98 instrument cluster or if its possible to remove and install a fuel gauge stepper motor. Really need some help on this one. Don't know what the dealer will say if I ask them.
