SF20 gas tank dimensions

[dcobbett]

The original tank that came out of my 1976 20SF measured 5' x 2' x 8" high. The hull has 2 main stringers.
I had a new tank built to those same dimensions and it holds about 48.5 gallons but I probably only have about 46 gallons of burnable fuel if you figure you can't suck the last 5%+/- out of the tank.
