Bad sending unit? Gauge reads half full.

I've got a gas gauge that ALWAYS reads half full. My gauge stopped working after I did a carb conversion. During the conversion, I replaced my tank with a sumped tank, but maintained my original sending unit. I eliminated the computer- does that have anything to do with the fuel gauge? I guess I'm gonna drop the tank and replace the sending unit, but find it kinda hard to believe that it decided to quit working after I swapped it out. Any input appreciated guys!!

I have read the stands are notorious for fuel gauge problems. Good luck with the fix

Mine used to read full tank until it hit 1/4 tank, then would read till empty, but it was still off as you could go quite a ways on "empty". But over the weekend it finally crapped out and just reads empty now.
