It wouldn't hurt to change the sending unit while you have it out. I changed
mine when I replaced the tank so I didn't have to deal with it later.
You should be able to get the tank out between the exhaust by unbolting the
rear hangers and pushing it out of the way as you bring it down. If it still
has fuel in it the weight can shift easilly but the suggestion of a floor jack
and board is a good one.
If I remember correctly, the only difference in sending units is the vapor
return line or lack there of. It is my understanding that the 396/350 had the
return line and the 396/375 did not. The return line runs along the frame with
the fuel line. Just order the one that is currently on your car.

Subject: [Chevelle-list] fuel sending unit
So I restored my dash over the winter, new fuel and temp guage. the dash turned
out great. However, my fuel guage is not accurate. I put 5 gal. in the tank and
it reads past full. If I have to drop the tank to check my grounds, should I
just replace my sending unit. And if so what sending unit do I need for a 70ss
396. It looks like dropping the tank is going to be quite a ordeal. I think I
am going to have to partially remove my exhaust. Thanks again yall for your
help. Bob
