ABSTRACT:
A fuel filter for the inlet of a fuel pump having upper and lower wall portions each constructed of a material with a plurality of openings. The lower wall portion has a greater total thickness and/or a smaller average opening size than the upper wall portion to provide more effective filtration of the fuel drawn into the fuel pump through the lower wall of the filter. The filter also causes a greater resistance to fuel flow through the lower wall thereby increasing the rate of fuel drawn through the upper wall of the filter.
