All, I am still working out the kinks of this old girl. 1993 380 Tournament Open. I have got to take her out the other day for a good old sea trial. Before I bought her, I knew she had the saddle tanks removed before. I was assuming that the main tank was much larger than it is. So what size was the main tank? I ended up measuring the tank and came up with about 350 gal. I then run the tanks down to almost nothing. 2" off the bottom. I could only get about 280 gal in the main tank. A real shocker. I need more fuel on the boat. So does anyone have the original measurements for those saddle tanks? How were the fuel lines run? What kind of fuel usage should I expect out of the 6-71 Detroit? Does anyone have a fuel curve? If I get a fuel bladder, does anyone know how much weight the bow might handle?
