A fluid flow baffle for fuel processors is described particularly adapted for fuel processors of the type having closely adjacent inlet and outlet flow ports. The fluid flow baffle separates incoming fuel from treated fuel to prevent contamination of the fuel processor\s filter device by heavy contaminants and water entrained within the incoming fuel. The baffle further improves the thermal efficiency of the fuel processor device by acting as an insulating barrier and by providing optimal flow patterns for the incoming and heated fuel. Several embodiments of the fuel flow baffle are described, one adapted for one type of fuel processor in which fuel flows through the filter element in a radially inward direction. Another embodiment relates to a baffle intended for use in another type of fuel processor having a fuel flow direction in a radially outward direction.

A unitary fuel processing and filtering unit, particularly for diesel fuel and operative to separate out water and impurities from the fuel adapted to be mounted to a mounting head having a fuel inlet passage and a fuel outlet passage comprising: a housing including a lower portion defining a combined heating and sediment chamber, a concentric annular shaped filtering means positioned within an upper portion of said housing, a top plate having a fuel inlet and fuel outlet, a generally cup-shaped baffle having side surfaces which extend along said filtering means whereby fuel flowing into said fuel inlet passage flows downwardly along the radially outer surface of said baffle and into said heating and sediment chamber, said baffle further defining a passage for conducting fuel from said chamber to said filtering means, characterized by heating means in said lower portion operative to heat the incoming fuel by direct contact therewith in said chamber, said heating means including a heated portion in close proximity to said passage, and said heating means extending through a substantial part of said lower portion.
