The Outlet Tube Assembly With Fittings attaches to the right Head. It is used on pumps older than 2013 or so. The tube is 3/8" hard black plastic. If you have a  newer pump that uses a 1/2" rubber flex hose, you need the High Pressure Hydraulic Hose.

Contents:

• 5 foot Outlet Tube
• Tee Fitting
• Straight Fitting
• Elbow Fitting

You might not need to use the fittings but they are included in case any of the pump fittings are worn out.
