Do diesel fuel filters also have one way check valves like those in oil filters?

If not, how about feed/primer pumps? Are they equipped with a one way valve? Or am I missing a fuel check valve along my fuel plumbing?

Up ko lang yung query ko.

Are there other users who experienced similar fuel back flow issues? Basically, the result is having to occasionally pump the feeder by hand till the fuel reaches the injection pump (pag bumigat na yung pump, it will start with one click). I'm using an FC321 but planning to change to a Baldwin BF7534 (4D56 application).
