How does a lawn mower vacuum fuel pump work?
A fuel pump is used when the gas tank is mounted lower than the carburetor and cannot rely on gravity to carry gas through the fuel line. Briggs & Stratton fuel pumps have either a plastic or a metal body and develop pressure using the vacuum in the crankcase, which is created by the motion of the piston.
Can you run an in tank fuel pump with a carburetor?
Any of our in-tank pumps can feed a carbureted engine provided that a bypass regulator is used. Because an EFI fuel pump can produce a large amount of flow, a bypass regulator is necessary in order to return the excess fuel back to the fuel tank.
