Tire bong, I lost mine in a move. Ot was a 4 ft loong PVC pipe with a cap on the bottom I drilled and taped to hook up a fitting for the hose (I used a hose off a can of fix a flat so I could screw it on the valve stem) On the top I used a clean out fitting to fill it with fluid. and a steel valve stem toward the top to hook my locking tire chuck to. Used the smallest setting on the regulator off the air compressor. Hook up the tire, fill the bong hook up the air and pump the fluid in.
gotta let it burp a few times.
