I was wonder how/if there is a way to add a vacuum style fuel pump to my briggs engine. It's an old 8hp made in 1986 on my snow blower. To make a long story short, once it gets a little below half a tank it starts to cut out and wont run. I have rebuilt the carb, (its spotless), cleaned and flushed the tank, replaced all fuel lines including filter, and checked the fuel cap. I have tried different carbs with no change and made sure the fuel lines are routed how they would be orginally. So anyway, can I add a vacuum pump somehow to this engine? Could I use crankcase pulse somehow? When the fuel level is higher it runs perfect. The tank sits in its orginal position still on the side of the engine and the fuel lines sit in all the brackets and not lower than the carburetor.
The old owner said they always had the same issue too. It's on an old Simplicity snowblower and uses an updraft carburetor. I also replaced all intake seals as well. Float height is set to spec, I even set it to allow a little more fuel in the bowl but no change. It also has a factory primer that physically squirts fuel into the intake manifold. I have replaced the primer too.
