Own a dirt bike, ATV, or side-by-side, or anything that you fill up?

Choose the right setup the first time.

• 1.25 gal – small tanks
• 2.5 gal – most riders
• 5 gal – high-volume refueling

Auto Stop Spout = most versatile. Shuts off before overflow.
Ripper Cap = fastest option for straight vertical tanks.

All sealed. No leaks in the truck. No guessing when to stop.
