Operate the priming pump (pump it up and down with your palm) "> until a small amount of fuel seeps from the vent valve. allow the pump to return upwards between pumps. When fuel is present, the filter is full of fuel and the system should be primed. 4. Close the vent valve. 5. Clean any fuel which accumulated on the fuel filter. 6. Start the engine and allow it to idle for a few minutes. 7. Check the filter for leaks.
