ABSTRACT:
A fuel pump improvement comprises a lip formed around the periphery of the open end of a fuel pump body. The lip is bendable over the outer margin of a diaphragm to form a fluid seal therewith. A second seal is provided between the diaphragm and the lip to seal against any fluid leak which may be created when the fuel pump is subjected to abnormal forces during a crash.
