Signs You Need a Replacement

If your equipment is showing any of these symptoms, the fuel line may be the cause:

• Fuel smell or visible wet spots — A cracked or perished fuel line seeps fuel. Diesel fuel lines harden with age and develop hairline cracks near connection points.
• Air in the fuel system — Air enters through deteriorated hoses, causing hard starting and rough running. Check all connections and replace any line that feels spongy.
• Collapsed line under suction — A reinforced fuel line can collapse internally, restricting flow. The engine runs fine at idle but starves under load.
• Fuel leaking at connection points — Old clamps lose tension and the hose shrinks over time. Always use new clamps when installing fuel lines.

Installation Tips

When installing new fuel lines, cut the ends square with a sharp blade — angled cuts cause leaks at the connection points. Use new clamps at every connection; old clamps have lost their spring tension. After installation, pressurize the system with the primer pump and check every fitting for dampness. Run the engine and recheck after 10 minutes of operation, as fittings can loosen slightly under vibration.

Frequently Asked Questions

How do I check if my engine code (SD16, WD10) matches?
The engine code is stamped on a metal tag attached to the engine block, usually near the timing belt cover or on the cylinder head. Compare the code you find with the list above. Engine codes are 3 to 6 characters long.

What material are these fuel lines made from?
This fuel line kit uses materials rated for the specific fuel type and pressure of your application. Diesel lines need to handle higher pressure than gasoline lines. Always install the correct fuel-rated line and use new clamps at every connection point.
