Fuel tank

[countshock]

I've done tons of searches, but maybe I'm not great at making this here search engine work.
I think the fuel tank on my '79 20'SF has given up the ghost. Tons of fuel in the bilge.
Looks like my summer is shot, since summer is my busy time at work (I'm properties & maintenance at a Yacht Club).
I'm looking for all the advice I can get on fuel tank removal on this boat. (Threads, pics, Dimensions of tank, advice on sources, etc.)
Like I said, I've tried the search function, but there is just too much out there! Ya'll have TOO much info!
Anyway, If anyone has any info they wanna share, it would be greatly appreciated.
It would kill me to miss the derby! (M.V.)
