New tank, Clean tank, or Fuel Cell?

It looks like someone shot some expanding foam up there. As far as the tank question goes, prices for new tanks have come down quite a bit in the past x amount of years. With that being said, before making a decision, I like to pull the tank and then make a decision on whether or not to reuse it.

Yes, there are kits to clean and coat your tank or you can have a radiator shop boil it out and seal it internally (again, if it passes a visual inspection). Of course, you need to weigh costs and time involved. In my case, all my tanks were in really good shape and were originals to the cars and I decided to reuse them and have them boiled out and coated. BTW: Pulling a tank/filler neck is a cake walk. It really helps to drain the fuel though. I have learned my lesson of removing nearly full tanks many years ago. Thank God I wasn't near an open flame.
