Craftsman Lawn Mower Fuel Line Replacement

OEM Craftsman Lawn Mower Fuel Line & Fitting Parts

Cracked or degraded fuel lines silently leak gasoline and prevent your Craftsman mower from running reliably. Genuine OEM fuel lines and fittings from Repair Clinic are designed to withstand ethanol-blended fuel and high temperatures without splitting or separating. We stock fuel lines in multiple diameters, reinforced hose assemblies, and barbed fittings for carburetor, tank, and fuel filter connections.

Don't risk fuel leaks or poor fuel delivery with worn lines. Quality OEM parts ensure your mower starts every time and runs clean all season. Find your correct Craftsman lawn mower fuel line parts by model number.

• Fuel drips from tank connection: Line cracked or fitting loose
• Mower won't start or sputters: Pinched fuel line blocking carburetor flow
• Fuel smell during storage: Line degradation or leaking at joints
• Fuel filter loose or separated: Worn barbed fittings or cracked hose
• Fuel line hardened or brittle: Age and ethanol damage — full replacement needed

Craftsman Lawn Mower Fuel Line Replacement: Questions & Troubleshooting

What type of fuel line does my Craftsman lawn mower use?

Most Craftsman mowers use 1/4-inch or 5/16-inch fuel-grade rubber hose with barbed brass or plastic fittings. Some models also have small diameter vent lines and primer bulb tubing. Your model number determines the exact hose diameter and fitting type needed. Never substitute with non-fuel-rated garden hose — it degrades quickly and can collapse under fuel pump pressure.

Can ethanol fuel damage Craftsman fuel lines?

Yes. Modern E10 gasoline (10% ethanol) hardens and cracks rubber lines over time, especially during off-season storage. OEM Craftsman fuel lines are engineered to resist ethanol attack better than generic alternatives, but they still need replacement every 2–3 years in high-ethanol regions. If your mower sits idle for more than a month, drain the tank and run a fuel stabilizer through the lines.

Do I need a fuel filter and fuel line, or just one?

Both are recommended. The fuel line connects the tank to the filter, and a second line runs from the filter to the carburetor. If you're replacing lines due to age or damage, replace both sections and the filter together — it's a single job and ensures clean fuel delivery throughout the season.

How do I match the correct fuel line diameter for my Craftsman model?

Your model number and engine spec sheet list the required hose ID (inner diameter). Enter your model into Repair Clinic's lookup tool, and we'll display the exact fuel line assembly and fittings your mower needs. Ordering by model number eliminates guesswork and help ensure fit.

Craftsman Lawn Mower Model Number: Where to Look

Craftsman prints the model number on a label attached to the mower frame near the blade deck on many walk-behind models. If you have a riding mower, check under the seat, on the rear fender, or on the frame below the steering column. You may also find the number on the engine housing, so clean away dirt and grass before reading the label. Type the complete model number into our model number lookup and the catalog narrows to parts made for your unit. This filters the full Craftsman lawn mower parts selection, not just fuel lines, to parts matched to your specific machine. You can order with confidence knowing the fit is right.
