By providing a fuel treating system with a strategically positioned sight-glass, it is possible to replace an fuel filter without either spilling large amounts of fuel all over or allowing for air bubbles, which can degrade the lubricating system's operation and cause siphoning. The sight-glass is positioned above the fuel inlet and outlet passages but below the filter. Thus, as soon as no fuel is seen in the sight-glass, a mechanic knows that the fuel filter has been substantially emptied of fuel yet the fuel inlet and outlet are still full.

[ That which is claimed:] [1.] A fuel treating system, comprising:a block, comprising:opposite upper and lower surfaces;an outer peripheral surface extending between said upper and lower surfaces;a first passage extending through said block;a second passage extending through said block;at least one through passage extending from said upper surface to said lower surface, wherein said at least one through passage excludes any obstructions therein, permitting fuel to flow freely from said upper surface to said lower surface or from said lower surface to said upper surface; anda bore extending from said outer peripheral surface to said at least one through passage;a fuel filter mounted to said upper surface of said block and in fluid communication with said first passage and said at least one through passage; anda sight-glass structure positioned below said fuel filter adjacent said outer peripheral surface and extending into said bore;wherein a mechanic can see if the fuel is in said through passage by looking at said sight-glass.
