1) Through the Sender or Fuel Pump via the access plate

An access plate is usually found in the trunk or under the back seat. (Pic2)  In this case under the back seat.

‧Remove the access plate and remove the pump / sender unit (Pic3).
‧Drop the fuel sensor into the tank.

NOTE: Generally most vehicle manufacturers recommend a new pump or sender gasket be installed when carrying out this process

2) Through the Neck of the Tank by removing the anti-siphon

The filler tube is connected to the neck of the tank by a rubber connecting hose.

‧Disconnect the hose and the filler tube.
‧The anti-siphon will either be inside the filler tube, attached to the neck of the tank or integrated with the tank neck.

‧Drop the fuel sensor down the neck of the tank.
NOTE: Some vehicles have screeens or curves in the filler tube which can block the sensor from getting into the tank.  A 5/8 OD diameter hose inserted into the filler tube to the tank can test to see if there may be any other blockages.

‧Remove the anti-siphon
‧Drop the sensor down the neck of the tank.

‧The fuel sensor cannot be dropped into the neck of the tank.
‧The fuel sensor must be installed through the sender or fuel pump.

3) Through the sender or fuel pump by removing the tank

NOTE: This method is only used if your vehicle does not have an access plate.

The tank should be as close to empty as possible. A full tank of fuel is extremely heavy and can cause injury. Either drain the fuel from the tank or wait until you have consumed the fuel before commencing your installation.
‧Disconnect all wiring and hose fittings associated with the tank.
‧Loosen or remove devices that secure the tank.
‧Remove or lower the tank.
‧Follow the instructions above relating to installing the sensor through the sender or fuel pump.

Installing the Air Sensor

The air sensor is installed in the air intake tube or inside the air filter housing. It is mounted on the pre-filtered (before the air is filtered) side of the air filter. It is held in place by the self-adhesive pad. ‧Find a suitable location.
‧Clean the selected area.
‧Attach the sensor.

Consider securing the sensor with a plastic cable tie as outlined below.
Be sure the location allows access to thread a cable tie around the sensor.
‧Drill two 2.5 mm holes on either side of the sensor.
‧Ensure the opposite side of the drill site is clear (Pic7).
‧Use an appropriate plastic cable tie to secure the air sensor (Pic8).

Install the Water Sensor


Use the metal clamp provided to attach the sensor onto the outside of the top radiator hose. Consider securing with a plastic cable tie (Pic9).

Final Step

Step 1

To allow the effects of the Fuel Saver to act on the fuel, the fuel sensor will need 30 minutes in contact with the fuel (Pic10) prior to Step 2.

Step 2

The Fuel Saver needs to be calibrated. Once calibrated the ‘Molecule Reaction Technology’ (MRT) is activated. The engine must be revved in neutral, alternating between 50% and 60% of maximum RPM to activate the system. This will complete the process.
Example: If the maximum engine speed is 7,000 RPM, alternate RPM between 3,500 and 4,200 RPM.

• Less than 2 years old and 18,000 miles, rev the engine for 2 minutes.
• More than 2 years old or 18,000 miles, rev the engine for 5 minutes.
