ABSTRACT:
A combination primer and pump for internal combustion engines which utilizes a flexible cylindrical housing having a flexing liner with unidirectional valves at each end. The walls of the cylinder permit manual flexing or squeezing to pump fuel and also a pulse connection in the outer housing serves as a valve to connect the crankcase pulse of an engine being supplied with fuel to the inner liner to permit pumping action to take place when the engine is running. The pulse connection may also serve as a control for the pulse pressure and thus for the fuel flow and pressure.
