RDS MFG INC Diesel Install Kit 11025 — Auxiliary transfer tank fittings for bottom gravity-feed diesel, leak-resistant seal kit

The RDS MFG INC 11025 Diesel Install Kit is a ready-made parts kit designed to connect an RDS auxiliary transfer tank to your vehicle’s OEM fuel system for reliable diesel gravity-feed fueling.

Many RDS transfer tanks are built to serve as auxiliary fuel sources, and the 11025 Diesel Install Kit supplies the fittings and components needed to integrate those tanks with a truck or van fuel system. This kit is optimized for diesel applications that use bottom gravity feed from the auxiliary tank; it also supports gasoline use only when fuel is drawn from the top of the tank with an electric pump. The kit simplifies installation while helping you maintain organized, leak-resistant connections between your RDS tank and the vehicle.

How does the 11025 kit connect an RDS transfer tank to my OEM fuel tank?

The kit includes the essential hardware to establish a fuel line pathway from the RDS auxiliary tank to the vehicle’s factory fuel inlet or feed point. It focuses on creating secure, sealed fittings that allow diesel to gravity feed from the bottom of the auxiliary tank into the OEM fuel system.

• Preselected fittings sized for common RDS tank outlets and vehicle fuel lines
• Sealing components to reduce risk of leaks at attachment points
• Compatibility with bottom-feed diesel installations for gravity flow

What are the kit’s limitations and gasoline usage guidelines?

This install kit is intended primarily for diesel gravity-feed systems. Gasoline can be used only when you draw it from the top of the transfer tank using a compatible electric fuel pump to prevent vapors and ensure safe flow.

• Diesel: supported via bottom gravity feed as designed
• Gasoline: permitted only when using a top-siphon electric pump
• Not a universal replacement for vehicle-specific fuel modules or complex EFI integrations

What will I find in the RDS 11025 package and what tools do I need?

The item ships as a single package containing the core fittings and components RDS recommends for an economical, straightforward auxiliary connection. Basic hand tools for hose cutting, tightening fittings, and mounting are typically all that’s required.

• One package with the full set of install parts for a single auxiliary tank connection
• Common hand tools (wrenches, hose clamps, cutter) usually sufficient for installation
• Follow vehicle- and tank-specific routing plans to avoid heat sources and sharp edges

Will this kit fit all RDS transfer tank sizes and vehicle types?

RDS produces tanks in a variety of capacities and dimensions, and this kit is intended to work with the majority of RDS auxiliary tanks that use bottom-feed outlets. However, fitment may vary with some vehicle models or aftermarket fuel systems; check your tank outlet type and vehicle fuel inlet before purchase.

• Designed to pair with most RDS transfer tanks with bottom-feed capability
• Confirm outlet thread and line size compatibility for your vehicle
• May require minor hose routing or adapter pieces for certain OEM systems

Who is this for: The RDS MFG INC 11025 Diesel Install Kit is built for fleet managers, contractors, farmers, and truck owners who use RDS transfer tanks for on-site refueling and need a straightforward, economical way to tie the auxiliary tank into their vehicle’s fuel system. Choose this kit if you operate diesel equipment that can gravity-feed from an auxiliary tank and you want a compact parts solution from the same manufacturer as your tank. If your setup requires electronic fuel metering, EFI adaptations, or top-siphon gasoline delivery, plan for the required pump or vehicle-specific adapters in addition to this kit.
