Dorman Fuel Line Repair Kit 83-Piece Tech Tray — Nylon & Steel Adapters with Installation Tool

Dorman 801-600 is an 83-piece nylon fuel line repair kit designed to let you replace damaged sections of fuel line quickly and accurately without removing the entire system.

If a short length of fuel line is cracked, corroded, or leaking, you don't have to swap the whole run—this compact tech tray contains the fittings and adapters to splice, adapt, and restore pressure-rated fuel lines on the vehicle. The kit combines single-piece connectors, quick-connect nylon unions, steel-to-nylon adapters and a specialty installation tool for angled fittings so most common repairs are done in-place with minimal downtime.

What components are included and why do they matter?

The tray delivers a broad selection of connectors and adapters chosen to match common fuel line configurations. Having the right parts on hand reduces trial-and-error and prevents multiple trips to the parts store.

• 83 total pieces: single-piece connectors, quick-connect unions, and elbow fittings.
• Steel-to-nylon adapters for connecting older metal lines to modern nylon hose.
• 45°, 90° and 180° angled connectors to replicate factory bends and clear obstacles.
• Specialized installation tool to seat angled connectors precisely and quickly.

How does this kit save time and money during repairs?

Rather than replacing long lengths of hose or removing rigid fuel lines, you can cut out the damaged segment and insert matching connectors from the tray. That targeted approach lowers parts cost and labor time while keeping the original routing intact.

• Replace only the damaged section instead of entire lines.
• Replaces corroded steel segments using steel-to-nylon adapters—no full-line swap needed.
• Pre-organized tray speeds parts selection and reduces diagnostic downtime.
• Tool included for quick, repeatable angled-connector installs on the vehicle.

Will these fittings work with my vehicle’s fuel system?

The tray covers many of the most common connection styles and includes adapters for older steel lines. However, fuel systems vary—always verify compatibility with your make, model and trim before installing to ensure correct fit and fuel-system integrity.

• Contains both straight and elbow connectors for typical OEM routing.
• Includes steel-to-nylon adapters to bridge legacy and modern materials.
• Use the manufacturer’s fitment tool or vehicle selector to confirm compatibility.
• Designed for on-vehicle repairs but follow OEM torque and safety procedures.

How do I install an angled connector with the included tool?

The kit’s exclusive installation tool helps position and seat 45°, 90° and 180° connectors cleanly without stressing the hose or fittings. Proper use yields repeatable alignments and reduces the chance of leaks from mis-seated connections.

• Cut the damaged section square and deburr the tubing/hose ends.
• Select the correct angled connector and adapter from the tray.
• Use the installation tool to hold and press the connector into place until fully seated.
• Double-check clamps, routing and a low-pressure test before full operation.

Who is this for: The Dorman 801-600 Fuel Line Repair Tech Tray is aimed at professional technicians, independent mechanics, and experienced DIYers who perform on-vehicle fuel repairs and want a compact, organized selection of OEM-style nylon connectors and adapters. It's particularly useful when you need to splice into older steel lines, restore factory routing with angled fittings, or finish a repair without replacing long runs of hose. Always follow vehicle-specific service procedures and fuel-safety precautions when using the kit.
