I have changed air dryers on trucks.
First of all you need to bleed all of the air out of the system
I believe yours should have a screw on filter correct?
did you get a purge valve kit and a heater kit?
I would recommend changing those as well.
Most kits have install instructions included.
you may need a snap ring pliers
