SELF-MOUNTING PNEUMATIC FUEL PRIMER

摘要

A two-piece self-fastening primer bulb structure for an internal combustion engine has a bulb of relatively flexible material with an annular mounting ring at a lower extremity thereof along with a base of relatively more stiff resilient material having a slotted rim for sealingly receiving the bulb mounting ring. The base is provided with a pair of self-fastening protuberances to be forced into an apertured support such as an engine housing or other panel deforming as they pass therethrough and reexpanding to secure the base to the support.
