Product Details
This aftermarket fuel line assembly with an integrated primer bulb is intended for use with compatible Yamaha outboard fuel systems. It provides an external fuel connection between the tank and engine and is designed as a replacement for assemblies identified by the Yamaha reference numbers listed below.
The assembly includes a primer bulb with an internal check valve to help draw fuel toward the engine during priming. Verify the connector style, hose size, routing and engine-specific requirements before ordering; horsepower and brand alone do not confirm fitment.
- Complete external fuel-line assembly with integrated primer bulb.
- Designed for quick installation where the listed connector configuration matches the original assembly.
- Primer bulb check valve supports one-way fuel flow from the tank toward the engine.
- Aftermarket replacement; not an original-equipment Yamaha part.

Engine Compatibility
This assembly is listed for a range of Yamaha outboard applications from approximately 4 HP through 200 HP, including selected 2-stroke and 4-stroke models. The broad horsepower range is an application guide only and does not establish fitment for every engine in that range.
Before purchase, compare the original fuel line, engine and tank-side connectors, hose diameter, hose length and fuel-system layout. Model, year, serial number and connector details should be checked together against the engine manufacturer’s parts information.
| Brand | Application guidance | Important fitment condition |
|---|---|---|
| Yamaha | Selected 4–200 HP 2-stroke and 4-stroke outboards | Confirm model, year, serial range and connector configuration. |
| Mercury/Mariner | May be usable on selected engines when the fuel-system connection is identical | Do not rely on horsepower or brand alone; verify the exact connectors and routing. |
| Johnson/OMC | May be usable on selected engines when the fuel-system connection is identical | Confirm the original part and connection type before ordering. |

Installation Notes
- Turn the engine off, work in a well-ventilated area and keep the assembly away from ignition sources.
- Relieve fuel-system pressure as appropriate and place an absorbent cloth beneath the connections before removing the old line.
- Compare the replacement assembly with the original line. Confirm hose direction, connector type and routing before installation.
- Connect the tank-side and engine-side fittings fully. Make sure each connection is secure and properly sealed.
- Position the primer bulb so its flow arrow points from the fuel tank toward the engine.
- Squeeze the bulb until it becomes firm, then inspect every connection and the full length of the hose for leaks before starting the engine.
Troubleshooting & FAQ
How do I confirm that this fuel line fits my engine?
Compare the original part number, engine model, year, serial range, hose size, connector style and routing. A matching horsepower rating by itself is not sufficient to confirm compatibility.
Which way should the primer bulb point?
The arrow on the bulb should point in the direction of fuel flow, normally from the fuel tank toward the engine.
Why does the primer bulb remain soft?
Check the fuel level, tank vent, bulb direction and both connections. Inspect the line for cracks, loose fittings or air leaks. If the bulb still will not prime after these checks, stop using the system until the cause is identified.
What are signs that a fuel line should be replaced?
Common signs include cracking, brittleness, swelling, fuel odor, visible leaks, a bulb that will not become firm or a loss of fuel prime.
Can the assembly be cut shorter?
Modification is not recommended. Cutting the hose can compromise the original fittings and create a fuel leak unless the work is completed with suitable marine fuel-system components and professional methods.
Is this an OEM part?
No. This listing is for an aftermarket replacement assembly associated with the reference numbers shown above. It should be compared with the original part before installation.
How should the assembly be maintained?
Inspect the hose, bulb and fittings regularly, especially before use after storage. Replace the assembly immediately if it shows damage, deterioration or leakage.
Safety & Important Information
- Fuel is flammable. Install and inspect the assembly only in a well-ventilated area away from sparks, flames and hot surfaces.
- Do not operate the engine if fuel leakage, damaged hose or loose connections are present.
- Verify the original part, connector configuration and engine-specific fitment before purchase.
- This is an aftermarket replacement and is not manufactured as an OEM Yamaha component.
- Professional installation is recommended when the correct fuel-system connection or installation procedure is uncertain.
