8. Note that the ESX Black Hose is not used at this time.
9. Start the vehicle, turn the Tee adapter valve counterclockwise to open it. Check for leaks.
Watch the Fuel Pressure gauge on the ESX control panel. A drop in pressure could indicate
a leak. If there are no leaks, note the fuel gauge pressure at this time.
-DIAGNOSTICS-
The fuel system is now ready to perform diagnostic tests if desired.
For instructions on how to perform these tests, refer to the Vehicle
Diagnostic section (see Page 23 ). If fuel system diagnostics are not
desired, continue with the cleaning procedure beginning with Step 10 below.
10. Press and hold the Fill/Purge button on the Keypad until the Fuel Level window indicates an
increase of 1/4 in the ESX fuel tank. If the vehicle stalls, turn the valve on the Tee adapter 1/8
turn clockwise. Restart the vehicle and slowly open the valve, by turning counterclockwise,
until the engine starts to stutter. Ease the valve back until the engine smooths and continue
filling. If the vehicle repeatedly stalls repeat this step until ESX fuel tank is 1/4 full.
11. Turn OFF the vehicle.
12. Add 8 oz. of RTI FUEL SYSTEM CLEANER, through the ESX fill port for every 1/4 added
to the ESX fuel tank.
13. Verify that the ESX Pressure Control regulator is completely open (counterclockwise). Press
and hold the Fill/Purge button for five seconds to relieve the pressure in the ESX Red Hose.
CAUTION: Flammable liquid can squirt out of pressurized fuel lines when connecting or
disconnecting. Always wear eye protection. Obtain zero pressure before
connecting or disconnecting any fuel lines or adapters. Always wear chemical
resistant gloves when connecting or disconnecting fuel lines. Wrap a shop
rag around the pressure point when connecting or disconnecting. Avoid
exposure to flames, sparks, hot engine parts, and/or ignition sources. By not
following the above cautionary steps the operator will be subjecting
themselves to serious injury or possible death.
