Key Features
-
Brass Rollover Safety Valve: The included brass rollover valve automatically shuts off fuel flow in the event of a vehicle rollover, providing critical safety protection that meets industry standards for auxiliary fuel system installations.
-
Brass Stop Valve with Manual Control: A durable brass shut-off valve lets you manually control fuel flow between tanks — open to allow gravity-fed transfer, close to prevent overflow or when the auxiliary tank is empty.
-
Complete Connection Kit: Everything you need in one package: 1 brass rollover valve, 1 brass stop valve, 1 diesel-rated fuel hose, 4 small hose clamps, 4 large hose clamps, and 1 roll of adhesive sealing tape.
-
Stable Gravity Fuel Supply: The gravity-feed design provides consistent, reliable fuel transfer from your auxiliary tank to the main tank without the need for electric pumps or complex wiring.
-
Aluminum Alloy Construction: Key connection components are made from corrosion-resistant aluminum alloy for long-term durability in under-chassis environments exposed to road salt, moisture, and temperature extremes.
-
Chevy/GMC Diesel Optimized: Specifically designed for 1999–2010 Chevy and GMC diesel trucks with 3/8-inch drain pipe connections — no guesswork on fitment.

Important Safety Notice
⚠️ Important: Always close the stop valve when the auxiliary tank is not in use to prevent fuel overflow from the main tank. This product is designed for diesel fuel systems only.

No installation instructions are included in the package — professional installation is strongly recommended.
Frequently Asked Questions
- Q: Do I need any additional parts to complete the installation?
- A: This kit includes all major components — valves, hose, clamps, and sealing tape. Depending on your specific truck configuration, you may need additional hose length, adapters, or mounting brackets. Professional installers typically have these supplementary items on hand.
- Q: Are installation instructions included?
- A: This kit does not include printed installation instructions. Due to variations in truck configurations and auxiliary tank setups, we recommend having a qualified diesel mechanic perform the installation. General gravity-feed installation guides are widely available online.
- Q: Can I use this kit with a gasoline engine?
- A: This kit is designed and rated for diesel fuel systems. The hose and sealing materials are optimized for diesel fuel compatibility. We do not recommend use with gasoline, as material degradation and safety risks may occur.
- Q: How do I know when to close the stop valve?
- A: Close the stop valve whenever the auxiliary tank is empty or when you do not need fuel transfer. This prevents potential backflow or overflow from the main tank. Monitor your fuel gauge during gravity-feed operation and close the valve once the desired fuel level is reached.
