07eins Performance Fuel Supply Kit (universal version for own connection)

Specially developed, universal mechanical valve control unit, which prevents the fuel lines to the cylinder head from running dry when the engine is switched 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.

• Universal mounting and application options using labeled connections
• Improved starting behavior, especially after a longer period of standstill
• Reduced diesel entry into the engine oil during longer starting processes

Version for universal use in any vehicle after its own connection to the respective fuel lines.

Alternative: Version for VW 2.5 TDI engines with quick couplings available in the shop. 

Background:

While driving, fuel from the tank continually circulates through the cylinder head and heats the entire fuel supply via the amount returned to the circuit. After the unit has been switched off, the physical effects of cooling the fuel can cause the fuel to withdraw from the cylinder head in the delivery lines despite the tank ventilation being intact.

The result is delayed starting processes with a longer running time for the starter motor until the engine starts.

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

The fuel valve kit uses threshold pressure valves to separate both the flow and return of the fuel lines from the tank and diesel filter after switching off, thereby ensuring that there is always enough fuel available directly in the cylinder head to ensure an immediate, clean engine start.
