I think I lost a post somewhere. I started thinking about the gravity fuel systems we use and finally did the calculations.
On my 3800, if I set the gravity feed tank on the roof of the cab, that gives about 1.04 psig at the carburetor(theoretically). To get 3.5 psig, the tank would have to be more than 11 feet above the carburetor.
I wonder how often the low pressure at the carburetor keeps the flow so low that the float bowl can't stay full?
