Frequently asked questions

Find answers to common questions about our products and services
  • A gravity kit relies on the natural downward flow of fluid from an elevated container rather than requiring an electric or mechanical pump, making it a simple, power-free dispensing solution with minimal moving parts and maintenance.

  • This kit is specifically designed for dispensing DEF (Diesel Exhaust Fluid), which is used in diesel-powered vehicles and equipment equipped with Selective Catalytic Reduction (SCR) emissions systems.

  • The 9' hose provides enough reach to transfer DEF from an elevated supply container down to a vehicle or equipment fill point without needing to reposition the container, giving you flexibility in your dispensing setup.

  • The manual nozzle gives you direct, hands-on control to start and stop the flow of DEF during dispensing, helping prevent spills and overfilling.

  • No, because it is gravity-fed, no electricity or pump is needed — the kit simply requires the supply container to be positioned above the fill point to allow fluid to flow by gravity through the hose and nozzle.
