Fuel Tank replacement

Looks like you got you hands full. There has been several threads about replacing tanks on this sight under the general section and under the repair section. Most of your questions would be answered there just look back and hunt for them. There are a few things I would say if I had to do the job over again. I would coat the tank with a epoxy coating, I would still use the plastic trips on the bottom of the tank to elevate it as indicated in some of the old threads, I would not use foam that’s what causes tanks to go bad. I would replace the old wood platform with a new one, and I would use a flat bottomed tank again. I know you are thinking of increasing gallons but the way to do that is by stretching the length. The reason why I say that on tank length is because the SeaCraft is a veritable dead rise hull design if you go with a V shape bottom tank there will be a downward angle to the tank at the bottom towards the bow of the boat at rest due to the V shape of the hull in the bow is much greater than in the stern of the boat plus due to the change in the angle of the V your tank would not rest properly on the hull in all places from the bow to the stern.
