Abstract
A fuel filter assembly (10) comprising an electrically non-conductive housing (12) with a layer (28) of electrically conductive material extending from the distal end (22) of an inlet connector (20) to the distal end (26) of an outlet connector (24) for conducting electrical charges completely through the housing (12) from distal end (22) to distal end (26). The housing (12) is fabricated by first forming an inlet half of the housing (12) with an opening and forming an outlet half of the housing (12) with an opening. The conductive layer (28) is disposed separately over the interior of the respective housing halves. Thereafter, the respective openings of the housing halves are fused together with the housing material fused together and the conductive layers (28) of the respective halves in electrical contact.
Claims3
A fuel filter assembly comprising;
- a housing (12) having a peripheral wall (14) with an interior and an exterior and extending between an inlet end (16) and an outlet end (18),
- said housing (12) including an inlet connector (20) integral with and extending from said inlet end (16) of said housing (12) to a distal end (22) and an outlet connector (24) integral with and extending from said outlet end (18) of said housing (12) to a distal end (26),
- said housing (12) comprising an electrically non-conductive material,
- a layer (28) of electrically conductive material extending from said distal end (22) of said inlet connector (20) to said distal end (26) of said outlet connector (24) for conducting electrical charges completely through said housing (12) from distal end (22) to distal end (26),
- said housing (12) including a filter support (30) extending inwardly from said outlet end (18) to a rim (32) and defining a passage (34) aligned with said outlet connector (24), and
- a second layer (50) sandwiched between said housing (12) and said conductive layer (28) and defining an extension (52) of said rim (32),
- said housing (12) being thicker than said conductive layer (28) and thicker than said second layer (50).
