The fuel pump is a mechanical pump they are fairly bulletproof. The one problem is when the pump and carb dry it takes a while to get fuel up to the carb.

There is a diaphragm that can fail, but it's rare. That's why there's a sight glass or clear hose coming off the pump. If there's fuel in that glass or line, you know you have a leaking diaphragm.

Why do you ask? Are you having problems?
