Dorman 3/8 in. Nylon Fuel Line — 10 ft Roll, Durable Abrasion-Resistant Replacement

Dorman 800-075 is a 10-foot length of 3/8-inch nylon fuel line engineered as a durable, direct replacement to help route and transfer fuel safely in underhood and undercar applications.

This nylon fuel line gives you a ready-to-cut length of dependable tubing for repairs, rerouting, or custom installations. Manufactured to resist common underhood stresses, it’s intended for use where original rubber or plastic lines have cracked, become porous, or developed leaks. Designed by Dorman with aftermarket experience and backed by technical support, the 800-075 line is part of a broader set of fuel line repair solutions suitable for many passenger vehicles and light trucks.

How does this fuel line hold up to underhood heat and abrasion?

The Dorman nylon formulation and construction are chosen to withstand typical underhood temperatures and contact with road debris. While specific operating limits depend on installation and surrounding components, nylon is commonly used for improved abrasion and chemical resistance compared with older materials. Proper routing and secure clamps further extend service life.

• 3/8-inch inner diameter for common fuel fittings and connectors
• Nylon construction resists chafing and wear from vibrations
• 10-foot length lets you cut custom sections for repairs
• Works well with standard fuel clamps and fittings when installed correctly

Can I use this line for fuel system repairs and leak fixes?

Yes — the 10-foot roll is intended as a replacement to address leaks or damaged runs when the original fuel line cannot be reused. It provides a straightforward material to splice into existing runs or rebuild a segment. Always inspect connectors, clamps, and other components, and replace any that show corrosion or damage to ensure a secure, leak-free installation.

• Cut to length for patching or full-run replacement
• Compatible with common fuel hose clamps and quick-connect fittings
• Use with approved fuel-compatible sealants and fittings
• Replace surrounding hardware if worn to prevent recurring leaks

What should I know about installation and vehicle compatibility?

Installation requires measuring, cutting, and securely fastening the new line in the vehicle’s routing path. While the 3/8-inch ID fits many fuel system applications, confirm diameter and fitting type against your vehicle’s requirements before cutting. If routing near hot surfaces or sharp edges, add heat shielding or protective sleeves to prevent premature wear.

• Verify 3/8-inch inner diameter matches existing fittings
• Use corrosion-resistant clamps tightened to manufacturer torque guidelines
• Avoid contact with exhaust, turbo components, or sharp edges
• Add protective loom or heat wrap where necessary
