    I recall this coming up on the old boards…. I check 12 -15 psi both ways… I use a bicycle pump with a home made contraption to pressure check, and a brake line bleeder and one of those yellow lower unit fill connectors to pull a vacuum.

    Frank I recall had the numbers, pretty sure he will correct my error, because I am not 100% positive. I usually do like 10 minutes for each as well….
