I have a 1973 Holiday I believe it is. My steel fuel tank is getting rusty on the bottom where it is sitting on the carpet. I was wondering if it is possible to get a new one that would have all the same connections for the filler and vent in either steel or plastic. It is a 12 gallon. Just found this site. Have had the boat for about 6 years but haven't used it for about 4 years because of bad shift cable that just got fixed. Hope to get it in the water this weekend.
