I found these vibration isloators in the Grainger catolog.( Grainger Industrial Supply ). Item # 2NPE3 - 1/4-20 female top x 1/4-20 stud on the bottom. You will need 4 they cost me $7.22 for all 4 shiped to me. I installed them between the pump and the bracket. ALL MY PUMP NOISE IS GONE! Thought all the members of Comp Diesel could use this info. I have an Air Dog, the FASS might be slightly differant on the mounting, but Grainger has many variations on these isolators available.
