Can I find out what size fuel tank is in the bottom of my boat by the hull no. If I can what Wellcraft site can I go to. It is a 1981 18 fisherman. I do have an access panel and the tank looks like it is about 4 Ana a half feet long and about 2 foot wide. I can't tell how deep it is I am in the process of removing it. I am just curios if Wellcraft goes back that far with the id's thanks
