Fuel Priming Pump (Typical Example) (1) Fuel priming pump (2) Purge valveThe fuel priming pump (1) is located on the top of the water separator.
Loosen the air purge valve (2) .
Push down on the top of the fuel priming pump plunger and release the fuel priming pump plunger in order to operate the fuel priming pump. Operate the fuel priming pump plunger in order to fill the new filter element. Continue to pump until increased resistance is felt or fuel starts to flow from the air purge valve. This resistance will indicate that the filter element is full of fuel.
Tighten the air purge valve.
Start the engine. If the engine will not start, further purging of air is necessary. If the engine starts but the engine continues to misfire, further purging of air is necessary. If the engine starts but the engine continues to emit smoke, further purging of air is necessary.
If the engine starts but the engine runs rough, continue to run the engine at low idle. Continue to run the engine at low idle until the engine runs smoothly.
