Guys, I need help.. i own a suntracker party deck '21. (deck boat). It's got a 4.3 mercruiser. I've recently picked up some bad gas. I am in the process of removing all the bad gas and cleaning the carburator. I don't have a manual for the boat yet. Can anyone tell me the location of the fuel pump? It's not mounted on side of engine, so I assume its in the tank. But, the tank appears to be not accessible.(inside hull)
