ABSTRACT:
The fuel pressure regulator has a new and unique means for integrating the filter screen and axially capturing one of two O-rings seals. A crimp and a shoulder on the outlet tube unite the outlet tube, the housing, and a washer that in one embodiment performs both the function of sandwiching the filter screen between itself and the wall of the housing through which the outlet tube passes and the function of cooperating with the housing in defining the groove which captures one of the two O-ring seals. The invention offers meaningful improvements in both manufacturing and cost.
