DIESEL FUEL SYSTEM SERVICE
FUEL SYSTEM CONTAMINANTS



During normal diesel engine operations
combustion contaminants build upon internal
engine surfaces.
This new diesel fuel system service removes
carbon, gum, varnish and other contaminants
from the diesel engine's fuel system and
combustion surfaces.
This service impoves diesel throttle response,
reduces smoke, and restores fuel efficiency.

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







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 solutoin, or exhaust fumes from the
engine.
Do not exceed the maximum canister air pressure of 40
PSI.
Always make sure that the Diesel Fuel Tool is hooked to
a secure fixture or set on a firm foundation.

DIESEL FUEL TOOL




Connects to the engine being
cleaned with adapters to the fuel
system inlet and return lines.
The engines fuel tank is replaced
with the 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 and the 1-5
micron filter on the machine.

1-5 MICRON FILTRATION

5” 1-5 Micron Filter Element
Housed Inside Tool

Twist top cap with wrench to
fully closed (metal to metal)

Always double check for
leaks

Replace filter after every
service
MINIMUM SOLUTION LEVEL




The minimum (base) solution level is
32 oz. Engine Clean Solution and
diesel fuel.
Do not allow the Diesel Fuel Tool to
run out of fluid during the cleaning
operation.
If the canister becomes empty, the
engine may suck air into the fuel
system and will be difficult to start.
In addition, the reserve solution helps
cool the injectors and high pressure
pump.

FILLING THE DIESEL FUEL TOOL







Unscrew the Filler Cap
Close the Shop Air Inlet
Valve
Add 1 bottle Engine Clean
Cleaning Solution
To prevent spills, fill the
Diesel Tool with the solution
very slowly and use a funnel.
Do not overfill
Re-install Filler Cap Wrench
Tight
Install new 1-5 micron filter
with each service

CONNECTING TO THE ENGINE

The diesel engine was patented in 1892 by Rudolph
Diesel. A key difference between early designs and
modern engines is the fuel injection system.

In modern diesel engines, fuel is delivered to the
diesel injection pump from the fuel tank by a
mechanical lift pump.

A high pressure injection pump (up to 26,000 PSI)
stores a reservoir of fuel at in a “common rail”.
Computer controlled injectors directly inject fuel into
the cylinders. Volkswagen, Dodge, Ford, and GM use
a common rail direct injection system as diagramed.

Excess fuel is used to lubricate and cool the
mechanical portion of the injection pump before
returning to the fuel tank.
Note: For detailed instructions regarding 1997 and newer
Ford Power Stroke, see page 14.

DISCONNECT THE FUEL LINES



Disconnect the fuel system feed supply
line. Preferably disconnect after the
primary filter. If you connect prior to the
primary filter, install a clean filter before
cleaning the fuel system.
Attach the appropriate adapter to the
engine side of the disconnected fuel
line.
Disconnect the return fuel line at a
convenient location. Install the
appropriate adapter to the engine side
of the fuel return line.
Fuel lines often accessible under
the vehicle near the drivers door or
at the under hood filter.
11
INSTALL FUEL TANK BY-PASS LOOP


A loop hose is included in the
adapter kit to re-route the fuel
tank supply and return lines.
Install the by-pass loop to the
tank side fuel inlet and return
lines when performing any and
all services.
12
CONNECT DIESEL FUEL TOOL

Using the quick disconnects attach the
adapters to their respective hoses on the
Diesel Fuel Tool. The red hose is the fuel
supply line and the black hose is the fuel
return line. Install air line to the Fuel Tool.

Increase the canister pressure to 7-15 PSI.
(Never exceed 40 PSI).

Slowly open fuel inlet valve.

Check for leaks & repair as necessary.

Clean up any spills.
13
EXCEPTON - FORD POWER STROKE

Ford diesel engines built before
1997 are conventional diesel
engines and have a single pump.

On Ford diesel engines built after
1997, each injector is a pump.

The injectors are supplied with
diesel fuel from an electric fuel
pump that is rated at 80-90 PSI.
14
CONNECTING TO 1997 & NEWER
FORD POWER STROKE ENGINES




Hook the Diesel Fuel Tool supply
hose (red) to the inlet on the electric
fuel pump.
Connect the return line from the
Diesel Fuel Tool (black) to the
engine fuel return line at the firewall.
Continue by isolating the fuel tank
with the fuel by-pass loop.
Always hook the tool to the fuel
pump. If you do not connect to the
electric fuel pump the engine may or
may not run. If the engine runs you
will have no circulation through the
Diesel Fuel Tool and no fuel cooling
or injector cooling.
15
START THE ENGINE




Let the engine idle until the air has been
worked out of the fuel system.
The engine should now run smoothly. If
it does not, check for loose connections.
Note: Once the engine is running
smoothly, the air pressure can be turned
off. Remove air hose press the
pressure relief valve and then slightly
loosen tool filler cap. The engine will
draw the solution from the tool canister.
Run the engine at 1200 RMP for the
duration of the service.
16
WHILE THE ENGINE IS RUNNING





Set a timer for 15 minutes
When the time has expired, check the fluid
level in the tool. Turn off the engine when
the fluid level reaches the base level, then
turn off the tool inlet valve.
Do not shut of the solution flow prior to
turning off the engine. If you shut of the
solution flow first, the engine may be
difficult to start.
Disconnect the Fuel Tool, reconnect fuel
inlet and return lines.
Start engine and check for leaks.
17
Simple Diagnostics

After 5 minutes of engine
operation write down the
temperature of each injector.

After 30 minutes write down
the temperature of each
injector.

Compare the temperature
differences by Cylinder.

If the numbers are
comparable, finish the
cleaning operation
18
AFTER SERVICE FUEL TREATMENT






After service, add Engine Clean
Diesel Fuel Conditioner and fuel
catalyst to the diesel fuel tank.
(treats 20-30 gallons)
Cleans entire fuel system.
Contains anti-gel and Cetane
improvement agents.
Removes sludge caused by
bacteria.
Disperses moisture.
Improves fuel storage stability
19
TOOL MAINTENANCE
The DIESEL FUEL TOOL requires
minimial maintenance.



Clean out the mixture tank after
50 services.
Periodically check connections &
fittings for tightness.
Inspect adapters for leaks &
replace if necessary.
