[Ed] got pretty creative with a hack that adds a pressurized water tap to his Jeep Wrangler. The tap on the rear passenger bumper now lets him hose off the vehicle after mudding, rinse his SCUBA gear after a dive, and just generally comes in handy.
If you want running water you’ve got to have a place to put it. This is actually what sparked the idea for the project. [Ed] noticed that the bumper was hollow and had some drain holes on the bottom. After plugging those and adding a fill hole to the top he found that he had a reservoir for about seven gallons. To get the water out he added a pump deigned to be used on an RV. It’s got features that make it work perfectly for this application: it runs off of battery voltage, it will turn on and off automatically when the tap is opened based on water pressure, and it will shut itself off if the reservoir runs dry. He designed a bezel to give the spigot a professional look. Just out of frame in the image above is an attachment for pressurized air. His next planned project for the Jeep is to add an air compressor.
After the break you can see a demo of the installed system, as well as a water pump test.
