Dorman 3/8 in Nylon Fuel Line — 10 ft Replacement Hose, Flexible & Heat-Resistant

Dorman 800-075 is a 10-foot length of 3/8-inch nylon fuel line engineered as a direct replacement to help restore fuel delivery and stop leaks.

This Dorman fuel line is made for mechanics, DIYers, and fleet technicians who need a tough, flexible conduit that survives harsh underhood and undercar environments. Constructed from resilient nylon and developed with aftermarket expertise in the United States, the 3/8" diameter tubing provides a reliable path for gasoline and other compatible fuels in repair and maintenance jobs. It’s sold in a convenient 10-foot length so you can cut to fit tight runs, splice into existing systems, or keep as a service-stock item.

How does this nylon fuel line handle undercar and engine-bay conditions?

The line is formulated to resist abrasion, heat cycling, and typical automotive contaminants, reducing the chance of cracks and leaks where routing and movement occur. Its flexibility makes it easier to route around brackets and suspension components without kinking.

• Resistant to wear from road debris and chafing at mounting points
• Maintains shape through repeated temperature changes
• Flexible enough for tight bends yet stiff enough to avoid collapsing
• Suitable for standard gasoline and compatible fuel blends

What vehicle repairs or projects is the 10-foot length best for?

Ten feet of 3/8" fuel line covers many common repairs: replacing short damaged sections, re-routing lines after aftermarket installs, or stocking a workbench for mobile service calls. You can trim exact lengths to match factory routing or create custom runs for modified setups.

• Patch or replace leaking sections without replacing the entire harness
• Custom routing for performance or lifted vehicles
• On-the-spot repairs for roadside or shop service calls
• Stocking for quick-turn maintenance on fleets or restoration projects

Will this fuel line work with existing fittings and clamps?

The nominal 3/8" inner diameter is compatible with common fuel-line fittings and clamps used in many gasoline systems, but always verify fitment with your vehicle’s specifications. For secure connections, use OEM-style clamps or crimp fittings rated for fuel applications.

• Pairs with standard barbed fittings and fuel hose clamps
• Trim ends squarely for a proper seal with barbs or quick-connects
• Use approved clamps or crimp sleeves to prevent leaks
• Confirm compatibility for ethanol-blended fuels where applicable
