Abstract
An in-tank fuel filter for securement to an in-tank fuel pump assembly includes a retaining or mounting ring which is utilized to secure the filter to the fuel pump assembly inlet. The mounting ring includes a collar which is received about the outlet stack of the fuel filter assembly and assists retention of the fuel filter assembly on the fuel pump inlet and maintains a fluid tight seal notwithstanding dimensional changes of the outlet stack occasioned by long term contact with fuel. The fuel pump assembly also includes a depending lug parallel to but offset from the inlet fitting. The mounting ring also includes complementary means to receive and grip the lug, namely, a plurality of resilient fingers arranged in a non-circular, i.e., elongate pattern such as an oval which compensates for inlet fitting to lug spacing variations and retains the fuel filter on the fuel pump assembly during subsequent manufacturing and assembly steps. In an alternate embodiment, the mounting ring collar and resilient fingers comprehend individual components.
