LVOUP Auxiliary Diesel Fuel Tank Installation Kit 11025 — Black, 1-1/2" Fill Cord, Aluminum Roll‑Over & Shut‑Off Valve

The LVOUP Black 11025 Diesel Installation Kit is a complete aluminum and rubber auxiliary fuel tank fitment set that adds a safe fill and drain connection for diesel trucks with a 1-1/2" fill cord.

This kit supplies the core hardware needed to connect an auxiliary diesel tank to many late-model domestic trucks. Built from anodized aluminum and resilient rubber, the kit includes an adapter tee, roll-over valve, shut-off valve with barb, hose, clamps, and PTFE tape so you can create a tidy, leak-resistant feed and drain location through the truck bed. It’s designed specifically for diesel setups that use a 1-1/2" fill cord and lists compatibility with a range of Ford, Chevy/GMC and Dodge model years; confirm fitment before ordering.

How does this kit create a safe connection for an auxiliary diesel tank?

The kit’s aluminum roll-over valve minimizes the chance of overflow when the vehicle or auxiliary tank shifts, while the adapter tee organizes the fill and vent routing. Components are anodized or rubberized for corrosion resistance and flexible sealing where needed. Properly installed clamps and PTFE tape help maintain a fuel-tight assembly.

• Includes aluminum adapter tee and roll-over valve for secure routing.
• Shut-off valve with barb lets you isolate the auxiliary drain quickly.
• Rubber hose sleeve and clamps protect hose connections from chafing.
• PTFE tape supplied for thread sealing on metal fittings.

What truck models and fill configurations is this designed to work with?

This kit is intended for diesel vehicles that use a 1-1/2" fill cord and accept a 3/8" female pipe thread drain fitting. The manufacturer specifies broad compatibility across popular domestic pickups, but you should verify physical dimensions and thread sizes against your vehicle’s existing plumbing before purchase. Special adapters may be required if your drain thread differs.

• For diesel systems using a 1-1/2" fill cord (model 11025).
• Compatible range includes many Ford, Chevy/GMC and Dodge model years; check specs.
• Requires a 3/8" female pipe thread drain fitting for the shut-off valve connection.
• Measure your factory fill line and drain threads to confirm fit before installing.

How difficult is installation and what steps are involved?

Installation is straightforward for an experienced mechanic but involves cutting the factory fill line and drilling through the truck bed, so professional installation is recommended. The core steps include placing the roll-over valve into the adapter tee, cutting and fitting the fill line, securing clamps, installing the shut-off valve into the auxiliary tank drain, and routing the hose to the roll-over valve while protecting sharp edges.

• Install roll-over valve into the adapter tee and position tee horizontally.
• Cut factory fill line and attach adapter tee with supplied clamps.
• Drill truck bed hole, deburr edges, and feed fuel hose to reach the roll-over valve.
• Install shut-off valve into auxiliary tank drain and use PTFE tape on threaded joints.

What parts are included and how do they improve long-term reliability?

The kit ships with everything needed for a basic auxiliary tank hookup so you avoid piecing together mismatched parts. Anodized aluminum resists corrosion and the rubber sleeves protect hoses from wear, while multiple clamps ensure secure joints under vibration. The shut-off valve adds a controllable break point for maintenance or transport.

• Aluminum adapter tee and aluminum roll-over valve for durable routing.
• Shut-off valve with barb, fuel hose, two rubber hose sleeves for abrasion protection.
• Four large and four small hose clamps to secure different connections.
• PTFE tape included for reliable threaded seals.
