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

Which Chevrolet models does this part fit?
Refer to the Vehicle Compatibility table above for the full list of Chevrolet models. Each listing includes the body type, engine, and production years. Match your vehicle’s engine code (stamped on the engine block) against the listed codes to confirm.

Can I cross-reference 800-888 with 02-03?
Yes. Both 800-888 and 02-03 are interchangeable OEM numbers for this part. They refer to the same component with the same specifications, just different part number revisions.

My vehicle is a 2002 model – is it covered?
The compatibility range for this part includes 2002-2003. The 2002 model year falls within this range, but verify the engine code and body type match. Mid-year production changes sometimes mean two vehicles from the same model year use different parts.

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.
