Prime the fuel system. Refer to the next topic.Priming the Fuel System
1. Unlock and pull out the priming pump plunger.2. Operate the pump to fill the new filters with fuel. Continue pumping until resistance is felt, indicating the filters are full of fuel.3. Push the priming pump plunger down and lock it.4. Start the engine and look for leaks around the filters.If the engine fails to start or continues to misfire or smoke, further purging is necessary. With the engine running, or with the use of the priming pump, loosen the fuel line nuts, one at a time, several times in succession and allow fuel to flow until free of air bubbles.
