1. 1 FUEL SYSTEM SERVICE ENGINE CLEAN FUEL TOOL MODEL RX 777

2. 2 FUEL SYSTEM SERVICE During normal engine operations combustion contaminants build up on internal engine surfaces. A fuel system service removes carbon, gum, varnish and other contaminants from the engines fuel intake, combustion, and exhaust system surfaces This service helps restore engine performance and restores fuel efficiency, and cuts emissions.

3. 3 SINGLE LINE FUEL INJECTED ENGINES  Single line fuel injection systems began to appear on the market in the early 1990's. They are found on almost all new vehicles.  With a single line system there is no return line and no circulation of fuel back to the fuel tank from the engine. This eliminates hot fuel from being dumped into the gas tank and limits harmful emissions from being released into the atmosphere.  On return less systems, injectors at the end of the fuel rail are prone to contamination and clogging. This can cause a lean condition and cause the engine to misfire. If engine emissions or drivability problems indicate a clogged injector, a fuel system cleaning is in order.

4. 4 SAFETY INFORMATION HAND & EYE PROTECTION Wear safety glasses when performing service. Wrap a shop rag around connectors before hook-up and disconnect to prevent fuel from spraying. Immediately repair any leaks in the tool or adapters. Keep all hoses and adapters away from moving parts and hot objects. Read and understand the material safety data sheet.

5. 5 MORE SAFETY INFORMATION  Perform service in a well ventilated area  Immediately clean up any spills.  Keep a fire extinguisher available.  Do not inhale or breathe the fumes from the machine, the solution, or exhaust fumes from the engine.  Do not exceed the maximum canister air pressure of 90 PSI.  Always make sure that the Fuel Tool is hooked to a secure fixture or set on a firm foundation.

6. 6 FUEL TOOL  Connects to the engine being cleaned with adapters to the fuel system inlet line.  The engines fuel tank is replaced with the mixture of fuel and cleaning solution in the canister.  While the engine is running at 1200 RPM, the cleaning solution is circulated through the engines fuel system.  Carbon and other contaminants are removed from the engine through the exhaust system.

7. 7 FILLING THE FUEL TOOL Unscrew the Tool Filler Cap Close the inlet Valve Add 1 bottle ECS Fuel System Cleaner To prevent spills, fill tool with the solution very slowly and use a funnel. Do not overfill Re-install Tool Filler Cap

8. 8 CONNECTING THE FUEL LINE Bring engine to operating temperature. Turn off engine. Loosen, or remove the vehicle’s fuel tank cap in order to relieve any pressure build-up in the system. Disable the vehicle’s fuel pump by looping the fuel lines back into the fuel tank, or disconnecting the wires to the pump, or removing the fuse that controls the fuel pump or de-activating the inertia switch (FORD). Disconnect the fuel system feed supply line.

9. 9 CONNECTING THE FUEL TOOL Hang the fuel Tool from the vehicle hood and attach to shop air. Attach the red hose to the engine’s port or via the fuel rail at the fuel test port or Schrader valve, or at the junction where the fuel supply connects to the fuel rail. If the engine is a two line system remove the clamp or plug from the fuel return line. Wrap a shop rag around connectors before hook-up and disconnect. This will prevent solution from spraying on the operator.

10. 10 PERFORMING THE SERVICE If a two line system, clamp or plug the fuel return line. Open the pressure regulator to 40 PSI. Open the ball valve and start the engine. Adjust the ball valve for the best idle. Continue to idle the vehicle until the engine nearly stalls. Turn engine off.

11. 11 DISCONNECTING THE FUEL LINE Reconnect the fuel line previously disconnected. Reconnect the vehicle’s fuel pump. Close the pressure regulator on the Fuel Tool and disconnect shop air. Press the pressure relief valve on the top of the fill cap to release pressure in the canister. Close the ball valve. Replace the fuel cap and tighten until it clicks. Start the engine & check for leaks.

12. 12 CLEANING AIR INTAKE SYSTEMS The option S-Sprayer tool is designed to clean vehicle air intake systems – throttle plate, plenum without opening fuel lines. This operation is usually performed after cleaning the injectors.

13. 13 CLEANING AIR INTAKE SYSTEMS  Hang the FUEL TOOL from the vehicle hood and attach the red line to shop air.  Attach the S-sprayer tool to the solution line.  With all valves in the off position, remove the filler cap on the top of the canister and pour 8 oz. of cleaning solution into the canister. Hand tighten the filer cap.  Remove the boot covering the fuel system air intake. Center the S-Sprayer in the center of the air intake. Reattach the boot if necessary to run the vehicle.

14. 14 CLEANING AIR INTAKE SYSTEM  Run the engine until it is at operating temperature. Open the cleaning solution supply line at 20 PSI for 30 seconds. Allow the engine mixture control to adapt to the richer mixture. Increase the pressure to  - 40 PSI for 4 cylinder engines;  - 60 PSI for 6 cylinder engines;  - 80 PSI for 8 cylinder engines;  Increase the engine RPM every 2-3 minutes for greater cleaning effectiveness and to suck up any excess solution.  Test drive the vehicle after the cleaning service to reset any computer trouble codes.

15. 15 TOOL MAINTENANCE The FUEL TOOL is designed to give many years of trouble free operation. Periodically check the machine for leaks and repair any immediately. If air is leaking from the center post of canister, tighten the center nut ¼ turn.
