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

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

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

• Universal installation and application options thanks to labeled connections
• Improved starting behavior, especially after long periods of inactivity
• Reduced diesel entry into the engine oil during longer starting processes

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

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

Background:

While driving, fuel from the tank continuously circulates through the cylinder head and heats up the entire fuel supply via the quantity returned to the circuit. After the engine is switched off, the physical effects of the fuel cooling down can cause the fuel in the delivery lines to withdraw from the cylinder head despite the tank ventilation being intact.

This results in delayed starting processes with a longer running time of the starter until the engine starts.

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

The fuel valve kit uses swell pressure valves to isolate both the fuel supply and return lines from the tank and diesel filter after the engine has been switched off, thus ensuring that sufficient fuel is always available directly in the cylinder head to guarantee an immediate, clean engine start.
