[QUOTE="MrGiggles, post: 482671, member: 22613"] I agree with Dale, sounds like it is only running on the prime and quitting once the bowl runs dry, not drawing anything up from the tank. Like he said, try squeezing the bulb as it's running. It should not leak anywhere. There is no purpose-built pressure relief, however the needle can be pushed off the seat if you apply enough pressure to the primer, causing the carb to overflow, but you really need to squeeze hard. The firmness that you feel in the bulb is from the carb needle shutting off fuel flow. I'm guessing that there is a hole in your fuel pump diaphragm, and fuel is leaking out through the vent/weep hole. [/QUOTE]
