Perform a fuel flow test. Disconnect the fuel line from the mechanical fuel pump in the engine
compartment. Have a second person catch any fuel that flows out of the line in a container with
accurate volume marks. Turn electric fuel pump on and pump fuel through the lines into
container. Ensure there is about 1 litre per minute flow rate.
NOTE: After carrying out the fuel flow test, check that both wing tanks are feeding fuel by
blocking fuel from both wing tanks, pumping about a litre out of the header tank, then allowing
fuel to flow from the left wing. The wing tank will gravity feed to the header tank, and it should re-
fill within approximately 1-2 minutes. This must be repeated for the right wing. If a wing is not
flowing correctly, check lines for kinks, blockages & airlocks.
