1st Gen Tundra
Fuel Line Kit

The 1st gen Tundra's fuel lines rot from the inside out — rust, cracking, and weeping at every connection. This kit is the complete fix: two replacement lines, four fittings, and four small EFI hose clamps. Nothing extra, nothing missing.

Everything in the box

Fuel Supply Line

High-pressure rated, fuel-resistant inner lining with reinforced braid. Replaces the corroded OEM section from the tank to the fuel rail.

Fuel Return Line

Low-pressure return side. Pre-cut to OEM length with correct wall thickness to handle the full temperature range of the engine bay.

Four Fittings

The four connection-point fittings that actually fail on this truck — supply inlet, return outlet, and both quick-connect ends. Exact-fit, no trimming required.

Four Hose Clamps

Four small stainless steel EFI hose clamps included with parts-only orders to secure fuel lines tight to fittings.

Backed by a real tech, not a warehouse

This kit was put together by Mopar Mike — a certified technician who has done this exact repair dozens of times and knows which corners get cut when the parts come in four separate orders. Order the kit and you get his direct line: get stuck on the install, text him a photo and he'll walk you through it.

Common questions

Does this fit both the V6 and V8?

Yes. The 3.4L V6 and 4.7L V8 1st gen Tundras share the same fuel line routing and connection points. The kit is spec'd for both.

My Tundra is a 2007 or newer — will this work?

No. The 2nd gen Tundra (2007+) uses a redesigned fuel system. This kit is specifically for 2000–2006 (1st gen platform). Reach out if you're unsure about your truck.

How long does shipping take?

Kit Only: ships within 1–2 business days from Springwater, NY. Most orders arrive in 2–4 days via USPS Priority.

Pre-Assembled: parts ship to Mike's shop first (allow 2–3 days in transit), then he assembles and ships to you. Total time is typically 5–7 business days. You get tracking for both legs.

What if I get stuck on the install?

Text or email Mike directly. You're not buying from a faceless warehouse — he has done this job and will help you get through it.

What's the return policy?

Unused, unopened kits can be returned within 30 days. Email inquiries@moparmikes.com to arrange it.
