Connecting Vapor Return Line to Vapor Shear Valve
Do not create any liquid traps when connecting the vapor return line to the vapor line shear
valve. See
Figure 3-17 . A liquid trap is a low spot in the vapor return line that can accumulate
fuel and cause blockage which could cause a system to fail vapor recovery certification tests.
Note: Contractor must provide and install pipe union for connection to 1-inch NPT coupling
in unit.
