Abstract: A filter element comprises a filter media and a restriction indicator device. The restriction indicator device comprises an attachment portion and a movable portion. The attachment portion is attachable to a portion of the filter assembly. The movable portion is movable relative to the attachment portion between a non-buckled position and a buckled position. The movable portion moves from the non-buckled position to the buckled position once a predetermined pressure drop between an upstream side and a downstream side of the movable portion of the restriction indicator device is met.

Abstract: One embodiment relates to a filtration system. The filtration system includes a filter housing and a filter element. The filter housing defines a central cavity. The filter element is disposed within the central cavity. The filter element includes a first endcap, a second endcap, and filter media. The second endcap is disposed axially away from the first endcap. The filter media extends axially between the first endcap and the second endcap. The filter media includes a filter media surface. A support element is in contact with the filter media. The support element is conductive. A first pole is along a surface of support element the filter media. The first pole has a first charge. A second pole is downstream of the first pole. The second pole has a second charge. The first charge is opposite in charge to the second charge.

Abstract: A valve lifter guide for internal combustion engines for preventing rotation of the valve lifters. The guide consists of an elongated support which is affixed to an internal combustion engine block, and spaced resilient cantilever supported fingers extending from the support have a free end which engages an orientation flat surface on the valve lifter and prevents valve lifter rotation. The resiliency of the fingers simplifies installation of the guide and assures engagement of the guide fingers with the lifter flat surface. An embodiment includes alignment features to facilitate assembly of the valve push rods.

Abstract: A fixture for positioning internal combustion engine rocker arm pedestals prior to bolting the pedestals to the engine. The fixture is a molded synthetic plastic body having recesses for receiving the rocker arm pedestals and fingers within the recesses maintain the pedestals therein. The fixture also includes positioning surfaces cooperating with engine components to assure proper positioning of the pedestals, and the fixture remains in the engine eliminating the necessity for removing the same after the pedestals are bolted in place.
