🔧 Fitment Tip – Plug & Barb Orientation (If Needed)
Depending on stock availability, you may receive a valve where the electrical plug or fuel barb need rotating to match your installation. This is a very simple 2-minute adjustment — here's how:
To rotate the electrical plug (solenoid):
- Mark the top silver solenoid body to the bottom screw-in section with a marker
- Loosen the silver section slightly until the plug rotates with almost no resistance
- Rotate the plug to your desired position
- Tighten the solenoid body until your marks align again
To rotate the fuel barb fitting:
- Grab the base of the barb fitting (not the barb itself) with pliers
- Twist to your desired orientation
💡 Easy DIY adjustment: This takes 2 minutes max and requires no special tools. Most customers won't need to adjust anything, but if yours does, it's a quick job.
