Hi - Does anyone know the dimensions of the original gas tank shipped with the 1977 Catlina 30s? Catalina doesn't have the drawings anymore and their specs changed in the early 80's. The previous owner of my boat replaced the tank with a Tempo 16.5 gal plastic unit but the fill hose and vent doesn't work properly - they sag. I've found a company that will build a new aluminum tank for me but need the specs and I'd rather not reinvent the wheel if I can avoid it. Thanks! Brian
