    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.
