The BFS 5 gallon gravity feed tank (part# NT2000G) comes complete with connector, flow indicator, and shut off valve.
This is an ideal system for filling only a few batteries at a time.
The gravity feed tank must be elevated by at least 5 feet to properly fill the battery.
The BFS shelf sold seperately, (part# S2000T) is a steel, powder coated frame that holds the gravity feed tank securely and can be mounted at the proper level.
