Sounds like your model has a back deck already ? Get a fuel tank ( custom built if needed ) that fits under your seat. Sounds like you need a bigger fuel tank or relocate tanks. I built my own rear deck on a 15' whaler, I built doors into the deck as to not have your issue. My fuel tank is under my seat ( 18 gal ) .
