Install the Toyota Truck Bed Rail Mount to secure your 4 Gallon WaterPORT Day Tank. Follow these steps for a stable, rattle-free setup on standard Toyota bed rails.
Quick answer
Mount the WaterPORT 4 Gallon Day Tank to your Toyota bed rail using the Toyota Truck Bed Rail Mount. Position the mount for balanced weight, tighten all hardware, and check stability before filling.
Why the right mount matters for your WaterPORT
A secure mount prevents your water tank from shifting during turns or rough terrain. The Toyota Truck Bed Rail Mount is designed specifically for the 4 Gallon Day Tank, so it clamps directly to standard Toyota bed rails without drilling. This keeps the tank accessible and leaves bed space free for other gear.
When this mount is not the right choice
This mount only fits the 4 Gallon Day Tank; it is not compatible with the 2 Gallon or 8 Gallon tanks. If you own a different size, you will need a different mounting solution. Also, confirm your Toyota truck has standard bed rails—some aftermarket bed liners or rail systems may not provide a suitable mounting surface.
Step-by-step installation
- Position the mount on the bed rail: Slide the Toyota Truck Bed Rail Mount onto the rail at your desired location. Choose a spot that balances the tank's weight and keeps it clear of cargo. Common mistake: placing it too close to the tailgate, which can interfere with closing. Check that the mount can slide freely before tightening.
- Attach the mount to the rail: Follow the included instructions to clamp the mount securely to the rail. Use the provided hardware and tighten evenly. Checkpoint: the mount should not rotate or slide by hand when tightened. If the mount feels loose, recheck that all bolts are snug.
- Secure the WaterPORT tank to the mount: Align the tank with the mount and fasten it according to the WaterPORT instructions. Ensure the tank sits flush and does not wobble. Common mistake: over-tightening the tank straps, which can stress the tank. Give the tank a gentle shake—it should stay firmly in place.
- Test stability before filling: With the tank empty, push and pull gently to confirm the entire assembly is solid. Then fill the tank and repeat the check. Checkpoint: no movement or rattling should occur during normal driving. Re-tighten hardware after the first trip with a full tank.
