Diesel engine fuel injector scavenge pipe with hexagonal header

The utility model relates to a diesel engine fuel injector scavenge pipe with a hexagonal header, one end of which is fixedly arranged on a fuel injector body (5); a header (2) of a scavenge pipe on the other end is fixedly provided with joint screws (1) of the scavenge pipe, and an external shape of the head of the scavenge pipe is hexagonal. When the diesel engine fuel injector scavenge pipe with a hexagonal header is installed, in order to avoid oil leakage of the scavenge pipe point, hexagons of scavenge joint screws and the header of the scavenge pipe are wrenched, and favorable sealing can be ensured. Simultaneously, the scavenge pipe can not be twisted off, and high-pressure injection requirements of the diesel engine can be fully satisfied.
