Homemade Air tank

For those of you who are wanting an OBA set up, and dont have room for a tank somewhere under/ in your truck. You can make your own removable tank out of a 2.5 gallon water pressurized fire extinguisher. This is the setup I followed (http://www.off-road.com/jeep/cherokee/2001/06_jun/airtank/)

Valve set-up:

thats a damn smooth setup kinetic.
all in all, what do you think the total cost was??

The total cost was about $40 with a regulator. The tank was a freebie :bigthumb:
