1969 20' 40gal fuel tank under console ques.

[Joe R]

I had the same hull..it had a 40gal alum tank under the console and under the front seat.The fill was on top of the console dash and vent on the side .. Later I had a replacement stainless tank made and rigged the same way it was like new when I sold the boat after 28 years.. See if you can fit a poly tank there, would be good above deck under the console....I just put a poly tank in my 1998 21 , I had to take the console off and cut the floor out.... Yours should be quick and ez to put a poly in that 20 under the console...(note CG regs no longer want fills and vents inside the boat ) I never had a problem on my old 20 just be careful filling/over filling
