Abstract
Abstract A fuel filter connectable in-line to a fuel system of an internal combustion engine has first and second separation means. The first separation means includes a reservoir in which fuel and larger contaminates settle and can be drained. The second separation means includes a baffle and screen mounted within a main body generally transverse to the fuel flow. A cap is selectively connectable to the main body to hold the screen in a set position and to further provide a passageway from the interior of the fuel filter to an outlet to the fuel system.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
206 words
A fuel filter adapted for use in a fuel system comprising in combination: a main body portion having a vertical axis passing therethrough and a relatively lower inlet connected to a fuel line in said fuel system and a relatively higher outlet connected in-line to said fuel line, said main body further including a reservoir therein having first separation means for draining said reservoir, said first separation means located at a bottommost location on said main body and in general alignment with said vertical axis, second separation means including a baffle plate having a relatively small number of holes passing therethrough and a screen spaced a relatively small distance above said baffle plate, said baffle plate and screen mounted in said main body at a position intermediate said inlet and said outlet; and a cap having an insert portion insertable within the main body and a skirt depending downwardly therefrom having connection means for connecting said cap to said main body, said insert portion of said cap adapted to seat against said screen and hold said screen into position within said main body and to further provide a flow passageway for fuel to pass from the interior of said cap and main body to said outlet.
