This is a 0-90ohm sending unit for the 4th gen gas tank swap in a 3rd gen in order for the gauge to read properly, some slpicing is required unless you use the Ractronix fuel pump kit-$80+shipping

I also have a carb'd 305 out of a 1984 Camaro Z28 H.O., the engine has 78,000 on it, it does burn some oil and has some leaks but runs good, local pickup only, I live in the Lancaster, PA area, comes with everything minus A/C-MAKE OFFER
