When you install the Direction Plus™ PreLine Classic pre-filter kit between the fuel tank and the O.E.M fuel filter, the pre-filter will remove 100% of water (based on 150μm droplet size) that is present in the diesel fuel. As a result, the O.E.M fuel filter will do the final and finer filtration ensuring you are maximising the protection of your diesel fuel system.

Also, the PreLine Classic has a transparent bowl, that allows to visually inspect the pre-filter for separated water and drain it if required.

Direction Plus™ ProVent oil separator protects your diesel engine by reducing the amount of oil entering the engine from blow-by gas in the crankcase ventilation system. By not fitting a Direction Plus™ ProVent system, it is likely that your engine will experience a progressive reduction in performance.

Direction Plus™ ProVent system is specifically designed to separate and redirect oil and air from blow-by gas produced from within the crankcase as it also provides the option of returning the oil back to the sump.
