(1) Plug
(2) Priming pump If the fuel system runs out of fuel or if air is introduced into the fuel system the following procedure may be followed.Note: The fuel system does not need to be primed after changing only the fuel filter. The engine will remain running after starting with a dry filter.
Do not allow dirt to enter the fuel system. Thoroughly clean the area around a fuel system component that will be disconnected. Fit a suitable cover over disconnected fuel system component.
After fuel is added to the fuel tank, remove plug (1).
Use a suitable container to catch any fuel that might spill. Clean up any spilled fuel immediately.
Unlock and operate hand priming pump (2) in order to pump fuel into the fuel system. This will also purge air from the fuel system. Stop operating the hand priming pump when fuel appears at the port.
Install plug (1). Clean up any spilled fuel immediately.
Operate the hand priming pump until a strong pressure is felt on the pump and you hear a click from the fuel filter base. This pressurizes the system with approximately 345 kPa (50 psi). This greatly reduces the cranking time that is needed to start the engine.
Push in and hand tighten the priming pump plunger.
Do not crank the engine continuously for more than 30 seconds. Allow the starting motor to cool for two minutes before cranking the engine again.
Crank the engine as soon as possible after pressurizing the system. The engine should start within 15 seconds. If the engine does not start after 30 seconds, stop cranking the engine. Repeat Steps 4 through 6.
