Attwood Mercury Fuel Line Kit - 3/8" Diameter x 6' Length (1998 & Newer)

The Attwood Mercury Fuel Line Kit in 3/8" diameter and 6' length is the OEM-grade replacement solution every Mercury outboard owner needs in their maintenance arsenal. Designed specifically for 1998 and newer Mercury engines, this fuel line kit addresses one of the most critical systems on your vessel—reliable fuel delivery from tank to engine. Whether you're a weekend angler running familiar coastal waters or a serious boater logging offshore hours, a compromised fuel line can strand you far from the dock. This kit eliminates guesswork by providing the exact diameter and length engineered for Mercury's fuel system specifications.

Marine fuel lines are engineered far differently than automotive counterparts, requiring materials that resist ethanol blends, saltwater exposure, and UV degradation. The 3/8" diameter specification ensures proper fuel flow rate and system pressure compatibility with Mercury's fuel injection and carburetor designs across their 1998-and-newer outboard lineup. At 6' length, this kit accommodates typical installation runs from deck-mounted fuel tanks to engine fuel ports, accounting for necessary routing around stringers and through bulkheads. Attwood's marine-grade construction means the line won't crack, swell, or fail under the thermal cycling and vibration loads that outboards experience during sustained operation.

Boaters with 1998 or newer Mercury outboards—whether 4-stroke or 2-stroke—should plan for fuel line replacement every 5 to 7 years as preventive maintenance, or immediately if you notice fuel odors, visible cracks, or performance hesitation under load. Installation is straightforward for those comfortable with basic engine compartment work, using standard fuel line clamps and barbed fittings. If your boat has been sitting, or if you've noticed sluggish acceleration or rough idling that fuel system cleaning didn't resolve, a fresh fuel line eliminates a hidden variable. This kit pairs perfectly with fuel filter replacements and tank flushing for complete system renewal.
