In-line fuel filtering device

Abstract

The in-line fuel filter device is readily installable in the fuel line of a liquid fuel-supplied engine. Thus, it is useful to filter fuels such as gasoline, diesel, oil, etc. and includes a generally closed, preferably cylindrical casing having a pair of opposed inlet and outlet-bearing endwalls interconnected, preferably releasably interconnected, by preferably transparent sidewalls. The casing defines a central filtering space accessible through the inlet and outlet. A preferably cylindrical particle filter is held by an interior bracket spaced from the casing sidewall with one end thereof surrounding and sealed against the outlet, while the filter is spaced from the inlet. A plate closes the opposite end of the filter and is secured to a bar passing longitudinally through the casing and filter releasably threadably secured to ferrules extending outwardly from the casing endwalls, so that the casing is readily openable. A ring magnet is secured around the inlet in the central space without impeding fuel flow therethrough and a coil spring bears against the magnet and plate to help hold the components of the device in tight engagement. The device includes pairs of adaptors, each having an internal passageway therethrough, one end of the adaptor being threadably receivable in the ferrules and the opposite end being of various diameters to facilitate connection to fuel lines of various internal diameters.
