Introduction
Congratulations on your selection of the CARBONCLEAN® DUAL SYSTEM. By choosing this product, you
are acquiring the most technologically advanced method available for cleaning harmful fuel system contami-
nants from gasoline & diesel engines.
The MCS 352 is a self-contained cleaning system, designed to connect to any gasoline or diesel engine (up
to 7.3L). Once the unit is connected, it temporarily replaces the regular fuel supply with a mixture of fuel and
the specially formulated CarbonClean® Cleaning Detergent.
With the engine idling, the unit pumps the fuel/detergent mixture through the vehicle’s fuel system. As the
mixture passes through the fuel system, it loosens and dissolves accumulated deposits, which then pass
harmlessly out through the exhaust system or are removed by the unit’s fuel lter. Removing contaminants
from the combustion chamber creates a more even burn of fuel, which improves horsepower, increases fuel
economy, and reduces exhaust emissions.
Please refer to the chart below for the recommended service intervals:

Wear safety goggles.
Wear chemical resistant gloves when connecting or disconnecting ttings and adapters.
Wrap a shop towel around pressure ttings and adapters when disconnecting.
Avoid exposure to ames, sparks, hot engine parts, and other ignition sources.
Explosion or ame or exposure to ammable liquid and vapors can cause injury.
The following process is used to ush factory testing uids out of your new machine, and is only necessary
before the rst time you use the unit.

Gas (Petrol) Service
Fuel System Types
Before beginning a service determine if the vehicle being serviced has a return or returnless fuel system.
Return Fuel System
A return system has 2 fuel lines, one from the fuel tank to the fuel rail and one returning to the fuel tank.
A regulator maintains the correct fuel rail pressure by returning any excess fuel back to the tank. These
systems work by having a pressure regulator at the end of the fuel rail that returns any excess ow back to
the tank. The regulator has a connection to the intake manifold to allow for a slight boost of pressure as the
throttle is opened. It is never recommended to deadhead a pump on a vehicle with a return fuel system.
[email protected] www.motorvac.com

Gas (Petrol) Service
Returnless Fuel System
The main advantage of this type of system is a reduction in evaporative emissions as excess fuel does not
get heated and returned to the tank. There are 2 sub categories of returnless fuel systems. Mechanically
controlled and electronically controlled.
Returnless (pressure controlled mechanically)
This is a typical returnless system seen on most vehicles since the late 90s. In this type of fuel system the
pressure regulator is part of the pump module, and all excess fuel bleeds off internally within the tank. It is
completely safe to ‘dead head’ the pump when connecting at the fuel rail because the connection is after the
regulator. This is essentially how the fuel system functions with the fuel rail being a dead end that only uses a
small amount of fuel under conditions such as idling.
Returnless (electronically controlled)
This type of system has pressure sensors at the fuel rail that feed back information to the PCM (power-train
control module). The PCM controls the pump speed with pulse width modulation to supply more fuel when
it is needed and less when it is not. The pressure is not constant in these fuel systems as the pressure target
changes based on engine speed, throttle position and ambient conditions. There is still a mechanical relief
in the fuel pump module but it will be set at the peak system pressure. Deadheading the pump on a vehicle
like this will not damage the pump but will likely result in unexpected behaviour from the vehicle as the PCM
will modulate the speed of the pump and not see the pressure it expects. It is never recommended to dead
head a pump in this type of system.
