Omega super charger 4500 psi leaking air

I have a brand new 7.5 hours (out of box was 5.25) omega super charger that is leaking air from bottom hole in back of unit. I was topping of my air tank and when unit got to about 3900 psi air started blowing out back of unit and would not quit. I closed tank and compressor will not build pressure. All pressure and air made leaks from bottom hole in back of unit. This is not the hole that bleeds of tank and hose, that is the top hole. That one is fine. The bottom hole looks to go towards the solenoid that activates the moisture bleeding process but could be wrong. Not to happy . Any suggestions ?
