ABSTRACT:
A fuel manifold for a gas turbine engine comprises manifold adaptors each supporting a nozzle for outputting fuel from a fuel supply. The manifold adaptors have a primary conduit and a secondary conduit extending between connection ends of the manifold adaptor. The primary conduit and the secondary conduit are in fluid communication with the nozzle to supply fuel thereto. Transfer units are between adjacent manifold adaptors, and each comprises a primary transfer tube matingly connected at opposite ends to the primary conduits of the adjacent manifold adaptors for fuel circulation between the primary conduits. A secondary transfer tube in each transfer unit is matingly connected at opposite ends to the secondary conduits of the adjacent manifold adaptors for fuel circulation between the secondary conduits. A drain sleeve in each transfer unit is connected at opposite ends to the adjacent manifold adaptors.
