It has the correct resistance sending unit for the stock gauge. It has a side fill. On the truck I did, I notched the top of the frame for the filler neck. Somebody else put a (5th gen) stepside bed on it and made the filler on the passenger side.
I also did an S10 Blazer tank once. 20 gal, side fill, correct GM stuff, also notched the rails to drop it in. I also remember notching a bed support right over the tank.
