'50 Gas Tank Replace or Repair?

[Bobert]

Removed the tank which is not leaking but has alot of chocolate colored sludge in it. Also can't get the sending unit out due to rusted phillips head screws. I a repro tank made for this car? (50 88 2 door sedan)If so who makes them and approx $?
Has anyone had experience, positive or negative, with RENU repair?
Should I expect that the sending unit is burned out since the car was started and run several times on 12 volts?
Thanks, Bob

give consideration to having a radiator shop look at your tank. they should be able to let it soak in a bath for a day or so. its worth a shot, because generally, it is just cheaper to repair than replace. i would think that the sending unit is okay, but the only positive way of knowing is to test it.
