Purple or Blue Loctite is highly recommended. We DO NOT recommend using Red Loctite.
Start by removing the elbow fitting on the left.
Turn the ram cylinder so you can better access the right fitting.
Now remove the right fitting.
Install the QEV on the ram cylinder. If the QEV does not line up correctly when tightened down use the supplied oring. A drop of Purple or Blue Loctite on the QEV threads is recommended.
Slide the hose onto the QEV fitting...
... and cut it to length.
Slide the elbow fitting onto the hose.
Screw the elbow down using a 1/4" socket or wrench. Again, a drop of Purple or Blue Loctite on the elbow threads is recommended.
The QEV will need to be turned slightly to allow the fitting to screw onto the gun.
