i am still chasing a leak at my drivers side front air bag.  so today i made up a new test jig.  

on mine i wanted the ability to release air from the bag and to add air to the bag independently.

it has 2 ball valves and 2 air gauges.  

the ball valve pointing down goes to an air chuck that i can put a shop air hose on to add air to the bag myself.  it is normally off.  

the other valve is in between the two gauges.  on mine i put real long air lines so the test jig is where i can see it on the floor without climbing up behind the bumper.  

the right side goes to the six pack

the left side goes to the airbag (really to the ping tank, then the airbag)

i took the line off of the six pack that goes to the drivers front airbag, put the tube from the left side of my jig on that line and the tube from the right side of my jig to the six pack.  

to start up i leave the valve between the two gauges open so the system works normally.  i aired up to travel height.  then i shut the valve between the two gauges off, isolating the airbag from the sixpack.  

i then start keeping a log of air pressures on both sides.    the gauges are not exactly the same accuracy (they are about 3 psi different from each other)

what is interesting is that my airlines to the ping tank are 3/8", but the fitting on the six pack is 1/4" and then the hose from the ping tank to the airbag is like humongo.  

using shop air to inflate that one side through my jig it goes up and down very quickly.
