2.5 GALLON AIR TANK & PLUMBING
The tank comes with six 1/4” NPT port openings to allow installation in many configurations on your vehicle.
To ensure safe and trouble-free use of your air tank, we strongly recommend that you install the supplied drain
cock and a safety pressure relief valve. (See Figure 1)
Tank Fittings:
Install the supplied fittings for the air tank in areas where they are most appropriate for your installation
using thread sealant or Teflon tape. (Not all installations will be plumbed exactly as shown in schematic.)
Make sure that the safety valve is installed in the top most position on the tank, and that the drain cock is
installed in the lowest position on the tank if the tank is to be installed in any other position than upright on
the tank’s mounting legs. Be sure that all fittings are accessible later in the installation process since you
will have to plumb air lines to each fitting as needed to utilize the air tank.
