Simplified Fitting Instructions

Installing an underslung tank typically involves:

1. Preparation:

   • Ensure the vehicle is safely supported (ramps/stands) and free of obstacles under the chassis.

   • Choose a location along the chassis frame where the tank sits clear of suspension, brake and fuel lines.

2. Mount Brackets (sold separately):

   • Attach the appropriate underslung tank fitting kit to the vehicle’s chassis rails — this provides secure anchor points.

3. Position Tank:

   • Lift the water tank into position on the brackets and align the pre-moulded threaded insert points with the fitting kit hardware.

   • Bolt the tank securely to the brackets, ensuring it does not contact other components or ground surfaces.

4. Plumbing Connections:

   • Connect the outlet to your freshwater system feed or waste discharge line via appropriate pipe/hose and clamps.

   • Fit a vent line to each vent port to equalize air when filling/emptying.

   • Use thread tape on BSP connections for a watertight seal.

5. Test:

   • Partially fill the tank with water, check all connections for leaks, then complete the plumbing once confirmed.

Tip: Always seal any drilled holes or exposed chassis metal to prevent corrosion, and route hoses away from heat or moving parts.
