Abstract
The present invention relates to a compact in-tank fuel pump filter which forms a portion of a fuel pump and filter module for a vehicle. The fuel pump filter includes upper and lower filter housing members which cooperatively receive the filter element. Both housing members and the filter element are contoured to partially wrap around the fuel pump housing in order to maximize filter area and contaminate holding capacity while minimizing total filter size. The filter element is preferably pleated paper but may be any suitable high capacity filter media. The lower filter housing member includes an outlet fitting which mates with a complementarily configured inlet fitting and is secured by releasable snap-lock assemblies. The inlet fitting receives a fuel pump housing and includes passageways which direct fuel to the inlet of the fuel pump. The fuel pump draws fuel through the filter element, through the open interior of the filter element and provides the fuel withdrawn from the fuel tank to the vehicle engine.
