Attwood Marine Johnson/Evinrude Fuel Line Kit, 6 ft x 3/8 in

Overview

The Attwood Marine Johnson/Evinrude Fuel Line Kit is a 6 ft x 3/8 in outboard fuel line assembly for Johnson and Evinrude fuel systems, offered with different tank-end connector setups and with or without a fuel demand valve. It is built around a low-permeation, fiber-reinforced fuel hose with a multi-layer primer bulb, giving boat owners a practical replacement line for portable tank and outboard connections.

The hose is compatible with ethanol-blended fuel and is rated for use up to 100 C. EPA certified and CARB approved construction helps meet current requirements for marine fuel systems, while the 3/8 in inside diameter supports the fuel flow commonly needed by larger outboards.

Key features

• 6 ft fuel line length gives enough reach for many portable tank layouts without leaving excessive hose loose in the cockpit or splashwell.
• 3/8 in hose diameter supports strong fuel flow for Johnson and Evinrude outboard applications.
• Low-permeation, fiber-reinforced hose resists kinking and hardening when used with ethanol-blended fuel.
• Multi-layer primer bulb helps with quick manual priming before startup after storage, refueling, or line replacement.
• Variant options include tank-end connector differences and a fuel demand valve option for systems that need added protection against pressure-related engine flooding.
• Sprayless tank connector configurations help reduce fuel spray when connecting or disconnecting a pressurized fuel line.

Variants

This fuel line kit is offered in three configurations. The main differences are the tank-end connection and whether a fuel demand valve is included.

Across the range, the kit is based on a 6 ft x 3/8 in low-permeation fuel hose with a primer bulb for Johnson and Evinrude fuel systems. Match the tank-end fitting and fuel demand valve option to the fuel tank and outboard setup already on the boat.

• 93806EUS7: Tank end 8838TM6 + 8838HF6, fuel demand valve no. This configuration uses the sprayless tank fitting and hose fitting setup without adding a fuel demand valve.
• 93806EUSD7: Tank end 8838TM6 + 8838HF6, fuel demand valve yes. This version keeps the same sprayless tank-end setup and adds a fuel demand valve for systems where pressure control is part of the fuel line setup.
• 93806ELP7: Tank end 8889LP6, fuel demand valve no. This configuration uses the 8889LP6 tank-end option and does not include a fuel demand valve.

Installation and fit

Check the tank connection, engine connection, and hose routing before installation. The 6 ft length works well when the portable tank is near the transom, under a seat, or in a nearby fuel locker, but it should still route without sharp bends, pinching, or contact with hot engine surfaces.

On sprayless connector versions, the tank fitting is intended for standard 1/4 in NPT fuel tank outlets. Threaded fuel fittings should be installed carefully so the connection seals without stressing the tank outlet or hose fitting.

Fuel system use

This kit is a good match for boat owners replacing an aging Johnson or Evinrude outboard fuel line where the hose has become stiff, cracked, swollen, or slow to prime. It suits fishing boats, runabouts, tenders, and small cruising boats that use portable or accessible fuel tanks and need a ready-to-install line assembly.

After installation, prime the bulb and inspect every connection before running the engine. Any smell of fuel, visible wetness, or loss of prime should be corrected before the boat leaves the dock or ramp.
