Bulk Tank Pressure Line
Installation of a bulk tank pressure line is required for the Auto-Fill Laser Pak to operate. The bulk tank
pressure line should be connected to the bulk tank vapor (low pressure) instrument line. This line is also
commonly used for the bulk tank pressure gauge. Follow the bulk tank manufacturer’s instructions for
removing the pressure gauge. A convenient piping installation is to thread a 1/4" pipe nipple into the open
port. Thread a female tee fitting on to the nipple. Thread a stainless steel compression fitting for 3/8” OD
tube into the branch of the tee. Thread the pressure gauge into the tee. Connect a 3/8” OD stainless steel tube
to the compression fitting. Stainless steel is recommended over copper to reduce the possibility of damage to
the tube. Run the tube to the bulkhead compression fitting located on the bottom of the Auto-Fill Laser Pak
control panel. Teflon tape should be used on all piping connections except tube compression connections.
Use leak check fluid on all connections. Be sure to open the bulk tank instrument isolation valves and close
the equalization valve after the installation is complete.
