5 Tanner deviated from the instructions and went with a 21/64 drill bit since that is what the tap kit calls for when drilling/tapping for a 1/8-inch NPT hole. The AIS instructions call for a smaller drill bit because the nozzles are usually inserted in the inlet tube that has thinner material. The AIS nozzle will grab the tube better with the smaller hole. The blower elbow has a thicker housing so Tanner went with the tap kit’s instructions. View Related Article
