Want to make sure that the plug to remove for tapping boost pressure is a 1" plug with a 1/2" drive..... TST's directions state that it is a 3/4" plug with a 1/2" drive to remove it. I pulled out the first plug behind the fuel filter and the 3/4" to 1/8" brass adapter supplied to me from TST is to small. The one removed was 1". Is this the correct plug?
