PURCHASED A PUMA PK-65 PUMP. AFTER VIEWING THE PUMA WEBSITE AND THE CS WEBSITE IT WAS DETERMINED THERE WAS A MAX RPM DISCREPANCY. I HAD ALREADY ORDERED A 3.5 INCH PULLEY, BUT IT WAS DETERMINED AFTER DISCUSSION, I NEEDED A 4 INCH. COMPRESSOR SOURCE ACKNOWLEDGED THE ERROR AND I WAS ABLE TO SEND THE WRONG ADVISED PULLEY BACK FREE OF CHARGE AND GET THE CORRECT ONE. SHIPPING WAS VERY VERY FAST AND APPRECIATIVE. THESE FOLKS ARE GREAT, BUT,I CANT SAY THE SAME FOR THE PUMP. THE WEBSITE SAYS 14-22 SCFM BUT I ONLY GOT 13.8 AT 90PSI USING THE WEBSITE CALCULATOR. I WAS HOPING FOR A BIT MORE, BUT I WILL DEAL WITH IT. I WISH I HAD WENT A DIFFERENT ROUTE ON THAT. BUT, WITH THAT BEING SAID, THE CUSTOMER SERVICE WAS SECOND TO NONE AND I WOULD GLADLY BUY FROM THESE FOLKS AGAIN.
