The 2 ½ gallon (9.46 liter) gravity feed tank is most popular for commercial applications.
NT2212GF - 2.5 Gallon Gravity Feed Tank
The 2.5 gallon tank ships with the 09FBLU1 connector unless otherwise specified.
When in use, it should be placed at least three feet above the batteries to ensure proper water delivery. Users often place the gravity tank on the roof of the golf car to ensure that there is plenty of height to allow the water to flow freely.
The watering system should always be disconnected from the water delivery device after filling. It should never be left attached to the watering system.
