It may pay you in the long run to replace the old tank with a new unit....
Aftermarket tanks run around $90 and new sender units and pickups run around $60 depending on how many pipes go into the tank...1 or 2 or 3...
If you do go with new tank, make sure you order the anti squeak strips...item 14 on the page.
See LMC page as an example
