Abstract
A fuel manifold includes a manifold block having a first port adapted to be connected to a main fuel tank, a second port adapted to be connected to an input connection of an auxiliary fuel tank, and a third port adapted to be connected to an output connection of the auxiliary fuel tank. A first channel in the manifold block couples the first port to the second port. A second channel couples the third port to the first channel and includes a check valve for permitting fuel to flow only from the third port to the first channel. A valve is coupled between the second port and the auxiliary fuel tank. The fuel manifold may further include a fourth port adapted to be coupled to the second main fuel tank. A third channel in the manifold block couples the fourth port to the third port. The fuel manifold further includes a constriction fitting attached to the manifold block for attaching a gas (nitrogen) line from the auxiliary fuel tank.
