Gino,
Great looking car and nice history. Welcome to the forum.
Regarding the sending unit from Steve; there are several postings on the forum regarding sending units.
Check out this posting for a company in Akron Ohio that rebuilds and gives a limited lifetime warranty.
I would suggest having a conversation with these folks to see what they would charge to look over/rebuild Steve’s unit.
It may be well worth the cost considering the cost/labor to drop the tank for a failed unit.
