not going to make any recommendations here but I'll tell you this, I wouldn't run it myself without knowing the test criteria or safety rating.. 125%, 2:1, ???

and it would seem you already have some doubt yourself based on this thread..

you have an FMVSS standard 121 air tank rated at 150psi max working and typical D2 governors are set to 135 max..

you're planning to run that system working at 135% of max rating and safety relief at 145% max rating..

things to consider; heat, condensation, cyclic duty, etc.. in other words, working it lightly or working it heavily?

my question would be, what does the compressor manufacturer recommend?

there are plenty of air tank manufacturers, anything else available with 200 psi rating that fits your application?

good luck!
