FILL-RITE 700V Serie Manual Del Propietario Y Operacion página 20

The pumps are shipped with a threaded vacuum breaker installed.
Fill-Rite recommends that the vacuum breaker be tubed back to the
tank. The vacuum breaker is used to break a siphon should an open
nozzle or a leaking hose be below the fluid level in the tank with the
pump turned off.
The following illustration shows methods of installing tubing for the
vacuum breaker that terminates in the vapor space at the top of the
tank. The tubing must terminate in the vapor space; if the tubing
terminates below the liquid level of the tank, the vacuum breaker will
not prevent siphoning. It is also very important that there are no
liquid traps in the tubing. The tubing must have a continuous slope
from the pump down to the tank. If the pump is installed below the
top of the tank, the tubing may slope both ways from a single high
point above the tank. Alternately, tubing can be piped to any
available opening on top of tank it the tank adapter is not used. Use
reducer bushings as required.

Fill-Rite recommends using the vacuum breaker tank adapter with a 1/4
npt opening in the side of the hex portion that terminates in the vapor
space of the tank. Install tank adapter per instructions found in this
manual. Make liquid tight connection from the adapter to the vacuum
breaker using a minimum of 1/4 metal tubing compatible with the liquid
being pumped. If a vacuum breaker tank adapter is used and the 1/4 npt
opening is not used for the tubing, plug the opening liquid tight.
