Non return valve on fuel system

Postby Luxy89 on Tue, 21 Jan 2020 1:25 +0000

Can anyone tell me if there is a non return valve located on the fuel line or housing? if so where is it located? 2013 D4D

There is a return line which sends excess fuel back to the tank but as far as I know no non-return valve. The common rail and ECU directs measured amount to the injectors and the excess is returned to the tank via a separate fuel line.
Why do you ask?

Sucking air or more likely supply pump failure, check the simple first... O ring on the filter... They are critical if not properly sealed.
