Sprinter 3500 V6-3.0L DSL Turbo VIN 45 (2007)
Fuel Filter: Description and Operation
DESCRIPTION
The fuel filter was designed for improved high altitude operation and for better re-start after the fuel tank has been completely emptied. The water drain
plug and water in fuel (WIF) sensor are located on the top of the filter. Water is drained by using the in-tank electric fuel pump to generate flow (attach a
hose to the drain plug). The filter has a pressure differential of 200-300 mbar (2.9 psi.) when new. When dirty, the pressure differential rises to 800
mbar (11.6 psi.).
