The Moeller 033319-10 is a universal in-line fuel filter built with a clear view housing so you can see fuel flow and check for contamination or water buildup without disassembling the filter. It provides 20 micron filtration and is rated for 85 PSI, making it suitable for filtering out dirt, debris, and other particulates before they reach the carburetor or fuel injection system.

This kit includes 3/8 inch, 5/16 inch, and 1/4 inch barb fittings, allowing it to be installed on fuel lines of different diameters without needing to source separate adapters. Because it is a universal in-line design, it is not limited to one specific engine or fuel system, and the clear glass housing lets boaters perform a quick visual check of fuel condition during routine maintenance.
