Well I am in the process of buying a 1993 b2150, I went to the guys house today to look at it and possibly buy it, well I get there and he couldn't get it started, he tells me he put a new fuel filter on it today but it has air in the system, well we tryed to get it bleed out and no luck, it never even sounded like it was going to fire. Any help on the bleeding process would help, I would really like to buy this thing but I want to here it run before. Please help me!
