Try it and see what happens, that'll really narrow things down.
Straight to ground want hurt it, same thing the sending unit is suppose to do at empty.
If it does bring the needle back down, sending units in trouble or tanks lost its ground.
Check it out, post back, and we'll go further.

Are the straps what ground the tank to the car? I am on my second sending unit from Summit and neither shows above 3/4 tank when it's full. Replaced the sending unit because the original developed a leak around the outlet tube. The gas gauge worked fine with the original unit. It doesn't seem to like these Taiwanese sending units. This is on my 1966 Lemans. Any thoughts?
Tomorrow I'm gonna take the original to the radiator shop & see if the can fix the leak..
