Abstract
Abstract A fuel processor device particularly useful for separating water and other impurities from diesel fuel. The fuel processor according to the invention features a vertically elongated housing where fuel is initially transmitted wherein water and heavy particulates are removed therefrom. The housing includes a manually or automatically actuated drain valve, a fuel inlet fitting, and an optional heating device. After passing through the housing, the fuel is conducted to a particulate filter, preferably of the spin-on variety, which is mounted to a head which communicates with a fuel processing housing. The filter is positioned in side-by-side relation with the fuel processor housing. A first embodiment according to this invention describes the use of a horizontal elongated head which communicates the upper portion of the housing with a filter mounting pad. A second embodiment of this invention is substantially identical with the first except that the unit is invented such that the lower portion of the housing forms the horizontal extending filter mounting pad. Fuel processors according to this invention provide excellent water separation and particulate filtration performance and are particularly adapted to be installed where vertical height limitations are imposed.
