Attwood Marine Fuel Line Kit, For Honda Engines, 3/8 in x 6 ft, EPA Compliant

Overview

This Attwood Marine Honda fuel line kit is a 6 ft. x 3/8 in. outboard fuel line assembly for Honda brand engines and tanks. It gives boat owners a ready fuel hose setup for portable tank installations, replacement fuel lines, and engine rigging where a 3/8 in. line is the correct size.

The kit uses a low-permeation fuel line with a multi-layer primer bulb and is listed as EPA certified and CARB approved. It is also compatible with ethanol blended fuels, which matters for many trailer boats, fishing boats, tenders, and other small craft that run pump gasoline.

Two configurations are available, with the main difference being the tank-end fitting arrangement and whether the tank fitting is included. This lets the same fuel line kit family cover setups that need a tank-side fitting and setups where the tank already has the required connection.

Key features

• 6 ft. fuel hose length with 3/8 in. inside diameter for Honda outboard fuel supply setups that use this line size.
• Low-permeation hose construction helps reduce fuel vapor loss compared with older conventional fuel lines.
• Multi-layer primer bulb supports manual priming at startup and after the fuel line has been disconnected or serviced.
• EPA certified and CARB approved configuration for current marine fuel system requirements.
• Compatible with ethanol blended fuels commonly used in portable marine gasoline systems.
• Available with or without the tank fitting, depending on how the boat’s portable fuel tank is already equipped.

Variants

This product is offered in two configurations for Honda fuel systems. Both use the same 6 ft. x 3/8 in. fuel line format, while the tank-end fittings and included tank fitting differ by variant.

The tank-end choice matters when replacing an existing hose or setting up a new portable tank. A kit with the tank fitting is useful when the tank side needs to be completed, while the no-tank-fitting version suits installations where the matching tank connection is already in place.

• 93806HUS7 includes tank end fittings 8838TM6 and 8838HF6, with the tank fitting included. This configuration fits a setup where the tank-side connection needs both the tank fitting and the hose-side fitting.
• 93806HLP7 includes tank end fitting 8902-6, with no tank fitting included. This configuration is for installations where the tank fitting is already present and only the hose-side tank connection is needed.

Installation and fit

Before installation, confirm that the engine and tank are Honda-compatible and that a 3/8 in. fuel line is appropriate for the outboard’s fuel demand and the existing fittings. Check the routing from the portable tank to the engine so the 6 ft. length can reach without tight bends, pinch points, or contact with hot engine parts.

Use a route that lets the primer bulb sit where it can be reached and oriented correctly during priming. After connecting the line, prime the system and inspect every connection for leaks before running the engine away from the dock or ramp.

Use cases on board

This kit is a practical match for small boats, tenders, skiffs, and fishing boats using Honda portable fuel tanks or Honda-compatible fuel connections. It is also useful as a replacement line when an older hose has hardened, kinked, or no longer primes cleanly.

Maintenance and care

Inspect the hose, primer bulb, and fittings regularly for cracking, stiffness, fuel odor, or seepage. Salt, sunlight, fuel residue, and storage heat can shorten the life of fuel system parts, so replacing a worn line before it fails is a smart part of routine boat maintenance.
