Has anyone had experience with the fuel pump housing having small cracks in it near the pulse hose inlet? My engine would start and run as long as you keep pumping the primer bulb, but would stall out after about 45 seconds if not squeezing the bulb. I took a fuel pressure tester to it, and no pressure! I then took the pump off and hooked a pressure tester to it, but could not get the pressure gauge to 15 psi as recommended per the manual. I could feel the air escaping from those cracks. Looks like its time for a new pump....anyone else had a similar issue?
