The Aqua Tank is a full washer fluid reservoir replacement that mounts snugly behind the grille of your 4Runner - Made out of 100% aluminum and tig welded for years of service. This system uses factory pumps and connections that have been sealed and pressure tested for optimum use. This product also features a Billet Aluminum threaded cap, fabricated right here in the USA. The install is extremely simple, and takes about 10 minutes start to finish. 

The Aqua Tank was designed to solve a common problem amongst Toyota 4Runner owners. After upgrading your tires and bumper, your plastic factory washer fluid tank is now exposed and prone to damage on the trails - not to mention it doesn't allow for optimum tire clearance when stuffing those big 35-inch tires under the fender. 

Disclaimer: Not all bumpers and situations are the same. Slight bending of the power steering cooler line might be necessary but not in all cases. Due to different applications some modifications might be necessary to aftermarket add-ons beyond our control.

  • Fitment is for 2014-2023 5th Gen 4Runner ONLY

  • Uses factory pump and connections

Fitment w/SSO slimline bumper

I have a lot of Rago gear, and really liked the idea of the Aqua Tank. Unfortunately, I couldn’t find a review at the time of purchase stating that it would fit my set up. I wanted to leave a review with the following info for those that may have similar mods:

- First, this thing is extremely well made
- This is installed on a 2018 ORP w/KDSS
- It fit with my SSO slimline bumper with the stage 2 high clearance option (purchased before the “versa” or “hybrid” naming existed)
- I have a Smittybilt XRC 9.5K GEN3 Winch
- I did have to remove the passenger side SSO stage 2 high clearance to install the Aqua Tank, but this might not be necessary if the install is done with two people and one of those people has a long reach/small hands.

Hope this helps others, and I’m happy with the upgrade.

Perfect Addition

Bought one to get rid of some rubbing. Fits perfectly and was pretty easy to install. Looks almost like it should have been there from the factory. Super sturdy. Painted mine black for the “stealth look” so it’s barely noticeable, but still love it!

Great Product !

This will work easily if you have a stock bumper. If you have a different bumper than stock it may be more of a challenge to install.
I have a Coastal Offroad Bumper and the way the video says to install didn't work because the larger base portion of tank was hitting
the support for the winch. I had to make a bracket that turned the unit 90 degrees and reroute the wires/hoses to make them reach.
After perfect and well protected !

Aqua tank

Aqua tank gives you more tire clearance by relocating behind front grill.

Best upgrade to achieve more clearance

When I upgraded to 37’s.. one of the area the rubs the most when I’m turning left is the washer tank. Eventually it started learning! Thanks to this upgrade I am able to relocate behind the grill and it’s super easy to install. 3 bolts to removed the oem and 2 bolts to install the new one! In my opinion, it looks better as well without the washer tank hanging there. Thanks for the expedited shipping as well Team rago!
