pretty sure you can get a new spring or a shim pack from your FASS dealer to adjust the PSI

Just pull the spring from the return line and physically strech it. I'm making 20psi with mine

I thought a shim kit was needed. Was that a trial and error "stretch"?

i replaced my spring to get my psi up to 21. i installed the shim kit too- that just reduces the noise of the fass pump a little.
