Rotorhead Posted August 23, 2022 Report Share Posted August 23, 2022 Hello All, My system has been running about 125 psi in both the forward and rear tanks. That should be normal, correct? Today after the parked regen was done I noticed the rear tank was about 130 or so. Just a little high. question is, is that typical once in a while? Thanks, Chuck Quote Link to comment Share on other sites More sharing options...
dennisvr Posted August 24, 2022 Report Share Posted August 24, 2022 !30 lbs is normal. Dont be surprised if you notice that both tanks aren't the same pressures, that is OK too. They have a double check valve between them.

Darryl&Rita Posted August 24, 2022 Report Share Posted August 24, 2022 Parked Regen added a bunch of heat under the truck, right near the air tanks. Rear tank gained more Temp than front.

Star Dreamer Posted August 27, 2022 Report Share Posted August 27, 2022 We have also noticed that the pressure is affected by the ambient temperature outside at least on our truck. Warmer temps seem to give us a higher pressure. I haven't paid attention to see if elevation makes a difference.
