A fuel pump priming system to prevent the obstruction of fuel flow from the fuel source to the intake of an internal combustion engine by having an alternate and path for fuel to flow between the fuel source and the intake of an internal combustion engine. This invention takes advantage of prior art using existing manual fuel system primer to pump fuel from the fuel source to the fuel intake of an internal combustion engine then after the engine is primed with fuel an adjacent but connected fuel line is then available creating an additional fuel path from the fuel source to the fuel intake of the internal combustion engine.

A fuel system includes a main fuel pump sub-system (MFP) with an inlet for receiving a supply of fuel from an inlet line. The MFP has a main outlet line configured to supply fuel to a main fuel throttle valve assembly (MFTV), and a cross-over outlet line. An augmentor fuel pump sub-system (ABFP) has an inlet connected in fluid communication with the cross-over outlet line, and an outlet connected in fluid communication with a main augmentor supply line. A actuation fuel pump sub-system (AFP) has an inlet connected in fluid communication with a branch of the main outlet line, an outlet line with a first outlet line branch configured to connect to supply fuel to the MFTV, and a second outlet line branch configured to connect to supply fuel to an actuation system.

A manually actuated feed pump is provided with a primer bulb to be manually actuated by an operator. The primer bulb has a pump chamber. A travel-controlled valve connects the pump chamber to a fuel line. The travel-controlled valve has a valve member that is moved by an actuation travel of the primer bulb into an open position that opens the travel-controlled valve. A first spring is operatively connected to the valve member and to the primer bulb. The primer bulb acts through the first spring on the valve member.
