Default Fuel tank on 23 cc

My 70 gal tank is seeping - water test not fuel - so I've got to get a new one. Wanted to move up to 100 gals but don't know if there is enough room. I have removed the aft well in my project 23 and the I/Os are also gone.
Has anyone done a V bottom tank and cut the platform out?

On my 23 CC I replaced my 100 gallon with a 120 gallon tank. Same H 12” and W 28” just longer 7’ if I remember correctly. It starts just in front of the CC just behind that deck hatch there and it runs to the 90 Degree turn in the stringers just about 3’ before the transom. The problem with a V bottom tank is the SeaCraft is a variable dead rise hull you might find that the front of the tank would have to be a different angle then the back of the tank to rest properly in the hull another problem could be that the tank could rest with a forward tilt again because of the variable dead rise thus you could have gas in the tank but at idle speed you might get air in the gas line and have the motor stop running even though you have 15 gallons of gas still in the tank.

Fellowship-- How much longer is the new tank than the old one? I want to put in a larger tank as well, but don't want to have the air problem.

Now this is coming from my memory and I am not as young as I use to be but the old 100 gallon tank was 12”H x 28” W x 69” long = 23,184 Divided by 232 = 99.93 gallons. The new tank is 12”h x 28” W x 84” long = 28,224 Divided by 232 = 121.66 gallons. Which is perfect length to fit in that space talked about above. I put a new deck in for the gas tank and also installed two bulk heads in one in the front and one in the back of the tank.

Should have said this is the method I used to install the tank. I also had the manufacturer of the tank weld two 90 degree brackets in the front and back of the tank that I screwed into the gas tank deck.
