Installation steps
1.First you have to make sure that your air tank is zero, and then exhaust all the air (if there is still air, it will be more troublesome to pull out the old high boost purge valve).
2.Take out the brake cleaner and clean the surroundings.
3.Use snap ring pliers to remove the snap ring, and then pull out the exhaust valve.
4.Put the silicone grease we provided on your finger, put it on the top of the drain valve, and smear it on the drain valve.
5.Rotate it and push it up, put in the snap ring, test. Snap ring can be compressed properly to adjust its size.
