There may not even be signs of leaking, since a fuel line leak on the tank side would have to be above the fuel level for leakage to show. Remove and check all fuel filters located in the fuel line and in the carburetor.
Why does hard priming slow down the fuel pump?

Why does my car accelerate when the fuel pump is not working?
When this mismatch becomes great enough, the pressure in your fuel lines can become inconsistent. In these circumstances, drivers may find their cars suddenly accelerating for a few moments even when they haven’t pressed the gas pedal, a condition known as surging. 5.
