Figure 3. Example FX tester connection to the Red Jacket pump
The FXT will be required for this procedure. The V-R FX2 Series LLD and the Snap Tap Connectors must be
installed before testing can begin. Refer to FX installation instructions 042-106-1.
1.
a. Connect the black hose of the FXT to the Snap Tap Connector at the tank test port of the pump. The black
hose is the path to the tank. Line pressure can be relieved through this path.
b. Connect the orange hose of the FXT to the Snap Tap Connector on the FX2 Series LLD. The orange hose
is the path to the line.
c. Turn FXT’s Selector Valve to ‘Pump/Line Pressure’ position as shown in Figure 4. When the selector valve
is in this position, the FXT is monitoring actual line pressure. As actual line pressure is displayed on the
compound gauge, specifications can be checked.
d. Observe pump operating pressure. This step may be done while dispensing is in progress. Check pump
operation specifications to verify pump pressure output and relief pressure.
e. From Table 1, below, select a leak rate at which to test. The top row of numbers (starting with 3) are the
choices, reflected in gph.
