To replace a fuel pump, stop the flow in the fuel line, and loosen the screws and hoses that hold the pump in place to remove it, says Briggs & Stratton. Use parts from a fuel pump replacement kit to install the new accessories, then install the new pump.
To stop the flow in the fuel line, twist the fuel valve to the off position or tighten a fuel hose clamp around the line, as directed by Briggs & Stratton.
Once the pump is removed, install the new diaphragm spring, cup and valve spring over the fuel pump chamber. Position a new diaphragm and gasket in the chamber, and return the cover. Secure the screws into place, and tighten each one with a torque wrench to a torque spec between 10 and 15 pounds, claims Briggs & Stratton.
Install the new pump where the old pump was installed, and use the mounting screws to secure it, as suggested by Briggs & Stratton.
The fuel pump is responsible for pushing fuel through the fuel line, according to Briggs & Stratten. It may be located near the fuel tank, directly on top of the carburetor, or between the carburetor and the fuel tank.
