i might be going to get some bolts tomorrow and thinking about getting a check valve, oiler, air filter, water/oil trap. for the oiler does it matter wut psi its rated since its on the suck side (im pretty sure it doesn't)?? and for the oiler if its before the check valve wut should the psi be rated since the only pressure is wut the compressor is putting out. my pressure switch runs 175psi max if that matters.
