Description
Why is it important to replace your fuel pump strainer regularly even though your fuel pump is functioning perfectly fine The fuel pump strainer (also known as pre-filter or fuel sock) is a fuel system's first line of defence against fuel system contamination; including dirt dust or other fine particles found in regular pump gasoline. Gasoline also has a tendency to varnish over time leaving a thick filmy layer over everything inside the tank--from the fuel pump internals to the tank walls and especially the strainer / pre-filter. A varnished or clogged strainer restricts flow forcing the fuel pump to work harder which affects pump longevity.
