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 a pulse connection in the outer housing connects the crankcase pulse of an engine being supplied with fuel to the inner, more flexible, liner to permit pumping action to take place when the engine is running. A pressure pulse passage between the outer and inner liner is positioned to be closed when the device is manually squeezed to achieve the priming function.
