How big is the fuel tank on a 98 26 Ft. American Offshore? Need to know asap. My Buddy bought the boat 2 weeks ago and the jackass said we could run 93 in it and we called the engine builder and he said we will have to run race gas with the pully set up on the blower. Had to pump out the 93 and I thought there should of been more gas than what I pumped out. Thought their was more race gas than pump but I must be wrong. Hope we didn't lean it out. What a dick to tell us to run pump gas.
