Dorman Fuel Line Repair Tool – Universal Nylon Fuel Tubing Cutter & Connector Kit (800-301)

If a section of nylon fuel tubing on your vehicle is leaking or cracked, the Dorman 800-301 Fuel Line Repair Tool gives a fast, cost-effective way to repair the line without buying a complete replacement assembly. The compact toolset is built to work with common nylon fuel lines and integrates into Dorman's broader lineup of fuel-line repair products so you can match connectors and fittings as needed. It’s geared toward DIYers and professional mechanics who need a precise, repeatable repair method.

How does the Dorman 800-301 save time and money?

Instead of removing and replacing an entire fuel line assembly, this tool lets you cut out only the damaged segment and install a connector or new section of tubing. That reduces parts costs and labor hours while keeping the original routing and mounts intact.

• Enables localized repairs—no full-line replacement required
• Works with common nylon fuel line diameters for wide compatibility
• Shorter repair times compared with full assembly changeovers

What functions does the tool perform during a repair?

The 800-301 provides clean, square cuts and secure joining capability so new fittings seat correctly and seals hold. It’s simple to operate, helping ensure a consistent result on each repair and reducing the chance of repeated work.

• Precision tubing cutting for leak-free joins
• Designed to pair with Dorman nylon fuel-line connectors and repair kits
• User-friendly design minimizes tool learning curve

Which fuel lines and vehicles is this compatible with?

The tool is made for nylon fuel tubing in a range of common sizes rather than a single proprietary line, making it suitable across many makes and models. Still, double-check tube outer diameter and material before proceeding to ensure a correct fit.

• Works on various nylon fuel-line sizes used in modern vehicles
• Compatible with Dorman replacement fittings and related repair kit parts
• A universal option for garages and mobile technicians

What support and guidance come with the product?

Dorman backs every part with access to their ASE Blue Seal Certified technical support team, so you can get application advice, troubleshooting help, and part-matching guidance if needed. The tool is also included as a component in Dorman’s Nylon Fuel Line Repair Kit for broader project needs.

• ASE Blue Seal Certified technical support available
• Included in Dorman’s multi-part nylon fuel line repair kit options
• Clear, repeatable operation reduces call-backs and rework

Who is this for? The Dorman 800-301 Fuel Line Repair Tool is aimed at DIY vehicle owners, independent mechanics, and fleet technicians who prefer to repair only the damaged portion of nylon fuel tubing. It’s particularly useful for anyone who wants a dependable, easy-to-use tool that pairs with a range of Dorman connectors and kits to keep repairs economical and professional-looking.
