Moeller Clear View In-Line Fuel Filter Replacement Cartridges, 20 Micron, 3-Pack - 033318-10

The Moeller Clear View In-Line Fuel Filter Replacement, part number 033318-10, is a 3-pack of glass-view in-line fuel filters built for boat fuel systems. Each filter uses a clear glass outer body so you can visually check fuel condition and flow at a glance, spotting debris, sediment, or water contamination before it reaches your engine's carburetor or fuel injectors. The 20 micron filtration rating traps fine particulates that would otherwise cause clogging, rough running, or premature wear on fuel system components.

Because this is an in-line design, it installs directly into the existing fuel line without the need for a separate filter housing or mounting bracket, making it a straightforward swap when replacing a worn or clouded filter. Selling as a 3-pack means boat owners can keep spares on hand or outfit multiple fuel lines without reordering. Each filter measures 1.63 inches in diameter, with a package footprint of 6.0 inches long by 4.13 inches wide, and weighs 0.1 pounds. Moeller Marine has built fuel system components for the marine industry for over 25 years, and this replacement filter is manufactured to the same standard as its original equipment.
