You can have very high pressure and very low flow, so that's not much of an indicator.
right...
i was just thinking that because there is no valve or anything on the 3/8" return line right before it goes into the pan (also being that there is a breather tube on the AW4) that the psi would be rather low being that the flow is slow
maybe i am wrong, not sure, i am real tired right now
also, 20 psi would pop the check level stick out of the tube, right?
