The fuel pump strainer (also known as a pre-filter or fuel sock) is a fuel
system's first line of defense against contamination from dirt, dust, or other
fine particles found in regular pump gasoline.
Gasoline has a tendency to varnish over time, leaving a thick filmy layer over
everything inside the tank. A varnished or clogged strainer restricts flow,
forcing the fuel pump to work harder which can lead to premature failure.
Within powersports applications fuel strainers need to be replaced more
regularly as they sit longer in the tank between uses. Quantum stocks a vast
selection of fuel strainers for both OEM replacement and Walbro fuel pumps. If
you do not see the strainer you need, please contact us directly with a picture
so we can source it for you.
