Abstract
A gas turbine engine fuel system comprises a main fuel manifold and starter fuel manifold which direct fuel into the combustion apparatus of a gas turbine engine. During normal engine operation, fuel flow to the starter manifold is prevented by a solenoid valve. Air from within the combustion apparatus then flows back through the starter manifold and into a fuel drains system of the engine to purge the starter manifold of fuel. This purging of fuel in the starter manifold engine operation prevents the undesirable leakage of fuel into the combustion apparatus from the starter manifold.
