Where is the culpret on a Daimler sprinter?
If you have access to a DRB (Daimler scan tool) check fuel pressure. You must have at least 2500 PSI to start. 3. If no or low fuel pressure the nasty little culpret may be a 25 cent o-ring. The fuel pressure regulator is located at the rear of the fuel rail on 2002 to 2004 trucks.
Where is the pressure regulator on a sprinter?
Pull out the fuel pressure regulator from the end of the fuel rail. Keeping the device clean, remove both the green O-ring and fibre backing ring from the tip of the regulator and replace with new components. Refit the regulator assembly to the rail.
