Project: running water YJ
 
I saw a fancy JK trick where the guy turned his stock rear bumper into a water tank that held a few gallons of water for a quick hose off on the trails before hitting the pavement and many other reasons. I want to do the same for my YJ! Problem is, I hate plastic and currently have badly misshapen bumpettes so looks like a build will come of this! I will admit, I dont have the expertise to weld this masterpiece on my own so I will need help for it but the idea is rather original so here goes.

The bumper will be a 4" by 4" square tube that tapers at the ends to match the look of the stock front bumper. From there, two D rings will be welded onto each end for recovery points and mounting plates will be welded on the opposite side to be able to bolt on stock. The top will have a hole with sealed screw cap for filling and similar on the bottom for drainage. The top center on the side facing the jeep will have a small hole for an air hookup line from my on-board air system. Next to the air pickup line will be a hose hose connection with internal rubber tube reaching to the bottom of the bumper. This hose connection will be for easy hook up of a marine coil hose line and sprayer. To have pressurized water, I will flip on my air compressor to compress the bumper allowing the water to come out at a force yet to be determined. If all else fails, ill hide a water pump under there somewhere and ditch the on-board air compression idea if the pressurized water flow is unstable or unsustainable.

Thoughts? Hope to have it all done just after christmas!

4x4 tube is not going to give you a very large water supply..I built tanks,larger than that to go on my welding trailers over the years.Mine would hold about 40 gallons full but I would only fill them about 2/3 full and then put 80 pounds of air on them before I left the shop to go on field service calls..They worked good for cooling steel and washing up after the job..

when farmers ordered fuel tanks from me,to figure approximate capacity,I would figure that each cubic foot would hold about 7 1/2 gallons..that will give you a close estimate to what your capacity will be

I love this idea! Can't wait to see what comes out of this thread

Harley I did the math and comes out to 4 gallons which should be good. Bit less than 4.... I figure a good strong flow out of the boat hose would be about 1 gal per minute or about 4 minutes of constant flow. The biggest I would go is 6"x6" which would be about 8 gallons of water but im not sure I would want the bumper to be that big, might look a bit clunky at that size.

Thank you! This might go dead for a little bit while I get all the angles squared away but I'm hoping to have the finished bumper done before christmas. Hopefully I can hint hint wink wink at the larger ARB dual compressor as a christmas present :) that should be able to hold about 150 PSI in the bumper for some good consistent pressure.

yeah,6x6 might look big but tapering the ends might make it look a little better..with good air pressure on it you could put a small tip in the end of the water line and have some great pressure without using a lot of water
