JkorkM Fuel Line Kit for Chevy Silverado & GMC Sierra 1999-2003 — Braided PTFE Hoses Complete Replacement

JkorkM 819-840 is a complete braided stainless steel fuel line kit designed to replace worn OEM lines on 1999–2003 Chevy Silverado and GMC Sierra trucks.

This fuel line set supplies flexible, PTFE-lined hoses wrapped in corrosion-resistant stainless braid and includes all clamps and a fuel filter to restore a reliable fuel delivery path. The kit is made to mirror factory lengths for the listed model years and trims, offering a more serviceable alternative to brittle or corroded rigid lines. It is suitable for gasoline and diesel engines and is sold with a 12-month warranty and responsive customer support.

Will this kit fit my Chevy Silverado or GMC Sierra?

Compatibility is focused on 1999–2003 Chevrolet and GMC full-size pickups, including 1500, 2500, 2500 HD and 3500 variants. Confirm fit by cross-referencing your vehicle’s year, model and the OEM part numbers listed in the product details before ordering. If you have an aftermarket fuel system or modified chassis, double-check lengths and connection types to guarantee fitment.

• Fits 1999–2003 Chevy Silverado and GMC Sierra 1500/2500/2500 HD/3500
• Replaces OEM numbers: 819-840, 819840, 15043857, 15765803
• Check factory line routing and connector types prior to installation

How does construction improve durability and leak resistance?

Each hose has a PTFE inner liner for chemical resistance and a braided stainless steel outer layer for mechanical protection and corrosion resistance. That combination resists dry rot, cracking and the rust common to older steel or nylon lines, reducing the chance of fuel leaks over time. Stainless braid also helps the hose maintain shape and protect the inner liner from chafing or impact.

• PTFE core for fuel compatibility and chemical resistance
• Stainless steel braid for rust prevention and abrasion protection
• Better leak resistance than standard nylon lines in older vehicles

What’s included and how easy is installation?

The kit ships with four braided fuel hoses sized to match the factory lengths, seven pipe clamp sets to secure connections, and one inline gasoline engine filter. Installation replaces factory clips with supplied steel clamps and routes the flexible hoses to the original routing points. While the hoses simplify routing compared with rigid tubing, professional installation is recommended if you’re not familiar with fuel system work.

• Contents: 4 fuel hoses, 7 clamp sets, 1 inline fuel filter
• Flexible lines reduce effort versus rigid replacements
• Installation guidance: use a professional for safety and proper sealing

Can I use these lines on gasoline and diesel engines?

Yes — the PTFE inner liner and stainless braid are compatible with both gasoline and diesel fuels, offering broad application across engine types. Even so, confirm pressure specifications and connector compatibility for high-pressure common-rail systems or specialized fuel pumps before fitting. If your vehicle uses factory high-pressure lines in the rail area, those sections may require OEM-specific components.

• Suitable for standard gasoline and diesel fuel delivery lines
• Check pressure ratings for high-pressure fuel rail sections
• Confirm connector types to avoid adapter requirements

Who this is for: This JkorkM 819-840 kit is intended for owners restoring or maintaining 1999–2003 Chevy Silverado and GMC Sierra trucks who need a more durable, flexible replacement than aged steel or nylon lines. It suits DIY mechanics comfortable with fuel-system work as well as shops seeking a complete replacement set that includes clamps and a filter. If you require guaranteed factory-original materials for high-pressure rail components, consult your mechanic before purchase.
