The short answer is no, the pump will pump gas until it reaches a pressure of around 3psi, then it stops (Mechanically cannot pump more). If you are finding fuel inside your engine, it will be a bad float valve in the carburetor. The only problem with fuel pumps is that they usually stop working, pumping too much fuel is not an issue!!

IF the float valves are good, then the only other possibility is the setting of the float heights. This is critical to the millimeter!

'Impossible' is just a level of difficulty! The only stupid question is the one you didn't ask first!
