Yamaha 15HP Fuel System & Carburetor Parts
A clean and stable fuel supply is essential for reliable outboard motor performance.
The fuel system delivers fuel from the tank to the engine and ensures that the correct fuel-air mixture enters the combustion chamber.
We supply Yamaha 15HP fuel system and carburetor parts for maintenance, repair and engine restoration.

Carburetor
The carburetor mixes fuel with air before the mixture enters the engine.
A dirty or worn carburetor may cause:
- Difficult starting
- Unstable idle
- Engine stalling
- Poor acceleration
- High fuel consumption
- Loss of power
- Irregular engine speed
In many cases, contamination or deposits inside the carburetor can restrict fuel flow.
Carburetor Repair Kit
A carburetor repair kit may include:
- Gaskets
- O-rings
- Float needle
- Seals
- Small internal components
It is commonly used when rebuilding an existing carburetor.
Fuel Pump
The fuel pump moves fuel from the tank toward the carburetor.
A weak fuel pump may cause fuel starvation, particularly at higher engine speeds.
Possible symptoms include:
- Engine runs normally at idle but loses power under load
- Difficult starting
- Engine stops at high RPM
- Insufficient fuel delivery
Fuel Filter
The fuel filter prevents dirt and debris from entering the carburetor.
Regular filter replacement can reduce carburetor contamination and help maintain stable fuel delivery.
Fuel Line Hose Assembly
A typical Yamaha fuel hose assembly may include:
- Fuel hose
- Primer bulb
- Engine-side connector
- Tank-side connector
- Hose clamps
Fuel lines should be replaced if they become:
- Hard
- Cracked
- Leaking
- Swollen
- Brittle
A damaged fuel hose can cause air leaks or fuel leakage.
Primer Bulb
The primer bulb is used to manually draw fuel toward the engine before starting.
If the primer bulb does not become firm, possible causes include:
- Air leakage
- Damaged check valve
- Loose connector
- Cracked fuel hose
- Fuel pump problem
