I just had to splice 2 wires inside the fuel tank when you install the new pump.It has been working great since april.

They started the updated fuel injection in 96. 95 still had tbi

Thanks for the correction!

It looks like the sending unit resistance is different between the tbi and vortec models also. 0-92ohms for the tbi and 40-250ohms for the gen 2 vortec.

I didn't encounter any problems with the sending unit. Got mine off ebay since my old one wasn't functioning. Came out of a Vortec injected 96 or 97. I simply put a new pump on it and reworked the wires to fit my original harness. It works beautifully. My gauge package is out of a 94.
