Rubicon Locker Pump PSI Test Results

I saw a thread about a week ago, but now I can't find it. Someone was asking for the PSI to inflate a Rubicon locker.
It was said to be between 5-8psi but some people were arguing that it had to be more than that. I thought I'd post a test result here today.

I was replacing an airline on a TJ Rubicon today and decided to hook up a lower pressure gauge to measure. Both pumps registered 5psi on this gauge.

Great information. The FSM says the same thing...I wonder who was arguing?

I wish I could find the thread.. perhaps it wasn't on this forum or was deleted.. I guess it might not actually resolve the argument because they were saying the locker could handle more PSI and it had to be higher because there was no way it could engage a locker at that level.

It started from someone who wanted to power their lockers from an ARB pump.
