Ordered Johnson Pumps 09-46839-01 Accumulator Tank from Amazon. User manual states it comes pre-pressurized to 0.8 bar which is ~11.6 PSI. When I checked the pressure, the tank was pre-pressurized to 8 bar which is ~110 PSI. The tank looks new unused so not sure what the deal here is. Anyway, if you are going to install new accumulator tank, check the pressure first, you might be as surprised as I was.
