[QUOTE="Pappy, post: 471151, member: 3278"] [size=5]Nope....fuel lines cannot siphon a fuel bowl dry. Yes, a primer bulb has a check valve in it. You should be able to blow through from the inlet to the outlet. That is how the primer bulb is able to fill the fuel bowl. What you have to remember here is that the engine does not need a fuel pump at all to run if you want to gravity feed it or just pump a bulb. All a fuel pump does is fill the fuel bowl...period. Once full it does nothing until the needle and seat drops and puts the pump back to work. The carburetor does all the metering and running of the engine. [/size] [/QUOTE]
