07eins Performance Fuel Supply Kit for VW T5 1.9 2.5 TDI engines

Specially designed mechanical valve control unit that prevents fuel lines to cylinder head from running dry when engine is shut off.

The fuel valve kit is designed to support the function of the pre-feed pump and replace missing/damaged or worn components of the factory fuel return system.

• Easy, tool-free installation in minutes thanks to matching fuel quick couplings.
• Improved starting performance, especially after extended downtime
• Reduced diesel entry into the engine oil during longer starting procedures

Variants:

To determine the appropriate variant of the performance Fuel Supply Kit for your vehicle, please check in advance which type of filter would be installed (with 2 or 4 connections). You will find all the necessary information in the "Selection guide" section of the Installation Instructions (German) or Installation instructions (English).

• PFSK-4: Version for use in vehicles with 4 connections on the fuel filter unit
• PFSK-2: Version for use in vehicles with 2 connections on the fuel filter unit
• PFSK-U: universal variant with hose connections (separate product) 

Background:

During driving, fuel from the tank continuously circulates through the cylinder head and heats up the entire fuel supply via the quantity recirculated. After the unit has been shut down, the physical effects of fuel cooling can cause the fuel in the delivery lines to withdraw from the cylinder head despite the tank vent being intact.

The result is delayed starting with longer running time of the starter motor until an engine start occurs.

Over a longer period of time, minimal amounts of fuel that were not burned during the delayed starting process enter the crankcase and can thus contribute to the well-known oil buildup with the associated consequential damage.

The fuel valve kit uses threshold pressure valves to isolate both the forward and return flow of the fuel lines from the tank and diesel filter after shutdown, thus ensuring that sufficient fuel is always available directly in the cylinder head to guarantee an immediate, clean engine start.
