The Seachoice 50-20941 is a universal clear-body in-line fuel filter designed for carbureted marine engines. Its multi-size connections fit 1/4 in., 5/16 in., and 3/8 in. fuel lines, making it a versatile replacement across a wide range of outboard and inboard applications. The clear housing lets you see filter condition at a glance during routine inspections — no guessing when it’s time for a change.

Compatible Applications

• Carbureted outboard engines using 1/4 in., 5/16 in., or 3/8 in. in-line fuel filters
• Carbureted inboard and sterndrive engines with compatible fuel-line connections
• Universal replacement for common in-line fuel filters across most marine engine brands

Fitment Notice: Confirm the existing fuel-line diameter and available installation space before ordering. This is a 100-micron universal filter — it is not the same as the Seachoice molded white 20-micron filters (50-21101, 50-21111, 50-21121) which are engine-specific and finer filtration. Not designed for fuel-injected engines.

When to Replace

• Contamination or discoloration is visible through the clear housing
• Restricted fuel flow causing hard starting or rough running
• As part of scheduled fuel-system maintenance
• Any time the filter housing shows cracking, leaking, or deterioration

Installation Notes

• Select the connection size that matches your existing fuel-line diameter (1/4, 5/16, or 3/8 in.)
• Use marine-rated fuel hose and appropriate clamps at both connections
• Install with the fuel-flow arrow pointing toward the engine
• Ensure both connections are fully seated and clamps are secure
• Inspect carefully for fuel leaks before operating the engine

Parts Desk Insights

The three things that distinguish the 50-20941 from other Seachoice fuel filters are the clear body, universal multi-size connections, and 100-micron filtration. It’s the go-to choice when you need a quick, universal replacement and don’t have the original filter part number on hand — as long as the engine is carbureted and the fuel-line size is 1/4, 5/16, or 3/8 in. The most common mix-up is confusing this filter with the white molded 20-micron series; the clear body and larger 100-micron rating are the easy tell. If the engine is fuel-injected or requires finer filtration, one of the engine-specific 20-micron filters is the right choice instead.
