4.6 sorry about that
Thanks, XXXXX XXXXX the low pressure port is located on the side of the drier/accumulator. If you do not know what that is,, follow the FAT/large diameter line from compresor to a black can per say. On the side you should see the fitting. It may still have a blue cap on it. Pic below shows the drier and you can see a small nipple/port on the side
