Bad Fuel Cell 1979 20 MA

[Vezo, Part II]

I was amazed to find nothing under tank to support it. Somehow they were able to get foam to expand less than half inch from floor in a couple of spots so that it was not making contact with floor at all. But you are 100% correct about foam holding water. Inspected tank to find no visible holes but in two places on aft end of sides, my buddy gently pushed on one corroded area and went right through. Both areas were located where foam was in full contact.

My biggest question is whether or not tank is original. 1979 MA, aft, (larger) hatch has a 5 inch square layer of glass only screwed into hatch for access to fill, vent and sender. Hatch has same hole with core removed. Reason is 90 degree fill is too high and would not allow hatch to sit properly. Major soft spot so I am recoring entire hatch and placing a Beckson plate over new fill. Do I need to have new tank built half inch shorter? Should I epoxy four half inch strips of mahogoney to place under tank?

You answered my next question of what type of foam to use when refitting. Thanks. Michael.

I have a few pics but cannot upload if anyone wants an email for the record.
