Priming the Fuel System
When an engine is new or has been completely run out of fuel it may be necessary to “prime”
the fuel system before attempting to start the engine. This means removing any air from the
fuel line. To prime:
•
Fill the fuel tank with fuel.
•
Remove the fuel line from the carburettor or fuel injector using pliers to loosen the
hose-clamp. Hold a container beneath the fuel line to catch any spilt fuel.
•
Place the fuel tap (A) in the “ON” position and allow fuel to flow out (into the
container) until no air bubbles can be seen in the fuel stream.
•
Push the fuel line back onto its connection point and re-fasten the hose clamp.
•
Clean up any spilled fuel. If fuel has been spilt, move the pump away from the
spillage before starting the engine.
•
Start the engine.
