Overview

The Attwood Marine 12562-6 is an inline fuel filter for carbureted outboard engines that uses 40-micron filtration and fits 3/8 inch fuel lines. It is a disposable high-flow filter with a clear housing, so you can inspect it in place without opening the fuel line every time you check the system.

This style of filter suits boats that run a simple inline outboard fuel feed rather than a larger spin-on canister setup. It helps catch debris before it reaches the carburetor and gives you a straightforward service point in the hose run between the tank and engine.

Key features

• 40-micron filtration for carbureted outboard fuel systems
• Fits 3/8 inch fuel lines used on many outboard installations
• Clear housing lets you inspect the filter without opening the line
• High-flow inline format that works with most outboard motors
• Housing resists impact and is shatter-resistant
• Disposable design keeps seasonal filter changes simple

Compatibility and fit

Check your hose size before ordering, since this filter is sized for 3/8 inch fuel line. It is best matched to carbureted outboard fuel systems where an inline service filter is already part of the hose run or where you are replacing the same style of filter.

For buyers comparing fuel filtration layouts, this unit is the compact inline type, not a remote spin-on water-separating assembly. It makes sense where space is limited and where quick visual inspection matters during routine checks at the dock or before a long day on the water.

Installation and service

Mount it in an accessible section of the fuel hose where the body can be seen and replaced without fighting other rigging. Keeping it visible makes it easier to spot contamination buildup during normal maintenance.

This filter is a good match for boaters who handle their own seasonal service on carbureted outboards. Replacing it during winter layup or spring commissioning keeps the fuel line fresh and gives you a clean starting point for the season.
