Mounts between the tank and the factory filter. The in-cab alarm tells you when water is in the fuel, so there is no manual checking.

• 100% water separation efficiency (Direction Plus figure, based on 150 micron droplet size).
• 98% particle separation (based on 30 micron particles).
• Remote multi-stage water alert, visual and audible, in the cab.
• Spin-on filter element for quick changes.
• No bypass, so contaminated fuel does not get through to the injectors.

Separates oil mist and blow-by gas before it enters the intake, protecting the turbo, intercooler and intake manifold from oil and carbon build-up.

• 98% oil separation efficiency.
• MANN+HUMMEL media, drain tap for oil collection.
• Optional return line to the sump.
• Regulates crankcase pressure.
• Reduces oil consumption where the oil is returned to the sump.
• Reduces exhaust smoke.

Check before ordering: the fuel filters are not compatible with Kaymar rear bars, and the fuel filter bracket may be an issue on vehicles fitted with remote reservoir shock absorbers.

2026 builds: the Direction Plus fitment table for this kit currently ends at 2025. Send us your VIN before ordering for a 2026 build.

Fitment per Direction Plus as of October 2026. Check the fitment guide or send us your VIN if unsure.

• We recommend a competent mechanic. Allow around 4 to 5 hours for both systems.
• PreLine-Plus mounts in the engine bay between the tank and the factory filter. The alarm module mounts in the cab (dash or A-pillar) and is wired in for the visual and audible alert.
• ProVent mounts in the engine bay and connects to the crankcase ventilation. The drain tap is routed for easy access and the sump return line is optional.
• Kaymar rear bar or remote reservoir shocks fitted, or planned: check clearances before you start.
• The two systems can be fitted together or separately.

• PreLine-Plus: drain when the water alarm sounds. Replace the spin-on element at your vehicle service interval.
• ProVent: check the oil level every 5,000 to 10,000 km and drain through the tap as needed. Replace the element every 40,000 km. With the sump return line fitted, oil recirculates automatically.

Q: Why is it not compatible with Kaymar rear bars?
A: The fuel filter mounting location clashes with Kaymar rear bar components. Direction Plus lists the fuel filters as not compatible. The bracket can also be an issue with remote reservoir shocks.

Q: Is this specific to the LC300 V6?
A: Yes. The brackets and fittings are made for the F33A-FTV 3.3L V6 in the 300 Series.

Q: Will this affect my LC300's performance?
A: You will not notice a power gain. It is protection: it stops the gradual loss that comes from carbon build-up and fuel contamination.

Q: Is the water alarm included?
A: Yes. The multi-stage in-cab water alarm comes with the PreLine-Plus kit and gives a visual and audible alert when water is detected.

Q: How does the PreLine-Plus differ from the Fuel Manager?
A: The PreLine-Plus is rated at 100% water separation (Fuel Manager: 95%), includes the in-cab water alarm and uses a spin-on element for faster servicing.

Q: Can I install it myself?
A: If you are competent with fuel lines and basic wiring, yes. Allow 4 to 5 hours. Otherwise any qualified mechanic can fit it. Installation guides are included.

Q: Does the ProVent return oil to the sump automatically?
A: Your choice. Run it as a catch can and drain it periodically, or fit the included sump return components to send the oil back to the sump.

Q: Do I need both systems?
A: They protect different things. The pre-filter keeps water and dirt out of the fuel system, the catch can keeps oil and soot out of the intake. Either can be bought separately, the combo gets you both in one order.
