Carb Vs. EFI fuel sending unit
Stock carb sending unit in my girls 86 Z28 floats- gas guage never reads level. Ran into this a few times with GM, replace sending unit and its OK but i cant find a new carb sending unit anywhere. I have another gas tank out of a TBI car with sending unit and pump. Has anyone converter an efi unit to a pick-up for a carb?
Was also thinking on just using the electric in-tank pump and a bypass regulator for the carb, but more leaning towards sticking with the mechanical pump for ease of use and not running anymore wiring and such

GTFiero, the following sticky should be all you need...

My 84 had a disintegrated sending unit, so I needed a new one. I found out that they make them for fuel injected 85 models and up but not for carbureted. I bought a sending unit for an 85 from Spectra Premium.
Look for part number FG20A. The boys at the garage had to weld on a stainless steel pickup where the in-tank pump would go. It's been working great ever since and I was able to keep my mechanical fuel pump.
