the return hose is the one that runs on the right side by the wheel.
the high psi line is the one that attaches to the pump with a fitting you remove the fitting with a 16mm wrench
the return line attaches to the pump with a hose clamp
Thank you for the quick answer I have one more related question though. Does the return line run next to another metal line?
This may help you.
Power Steering Pressure Pipe/Hose Replacement (3.4L)
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
