Connect the wiring harness to a voltage source of 12 VOLTS maximum with a negative ground only. Install the additive tank on the outside of the engine compartment.
Connect the wiring to 8L5000 Switch (1) so that the system can be activated with the starting motor switch in the OFF position. Keep the additive tank full when not in use. This will prevent damage to the system and components by corrosion when not used for long periods of time.Operation: Just before the engine is started, push the switch to activate the system; this will let the additive flow for approximately two minutes, through an orifice connected to the fuel supply line of the Sleeve Metering Fuel System. The fuel transfer pump then pulls the additive into the system along with the Diesel fuel. The system can be again activated if necessary. The engine can be started approximately three to four times per liter (fifteen to twenty times per gallon) of additive.Maintenance: Keep the additive tank full when not in use. This will prevent damage to the system and components by corrosion when not used for long periods of time. Install a new injection group filter (9N3778) at six month intervals or when the filter becomes plugged (full of foreign material) so additive will not flow through it.
