Finally back at it again. Went down to Ace hardware J&B Boats and bought some parts needed for contructing the tanks. Change of plans as far as the design goes. Decided to put the fuel gauge sender and vent near the fuel fill for ease of construction and future mantenance. Being that I had to put a gasket around the fuel sender anyway and the sender went in the side of the tank I figured one hole at the fill for all three, with a gasket, would eliminate a lot of welding headaches. Pictures are forthcoming, makes my life a lot easier to say the least and I actually like the design much better, everything except the outlet and drain are all at one place under a nice flushmounted deckplate that I also bought at J&B.
