Note:
You might need to slightly rotate or twist the needle to ensure that it routes straight
down the channel before tightening the screw on the needle-tubing clamp.
24. At the needle-tubing clamp, bend the needle to the right, toward port 4 on the injection
valve.
Tip:
Use a small, rounded tool (such as a T10 TORX driver) to aid in bending the tubing.
