M817 pump problem

[smoothnu]

My 250 seems like it is sucking air by the way it is acting. I tried replacing the filter but to no avail. I finally tried bypassing everything by placing the fuel line directly into a jug of fuel and it still has the same symptoms. Does anyone have any ideas as to what is going on?

Try putting the question in the 5ton foruum?

Replace the rubber fuel line.

Also check the filter bolt is sealed correctly(square washer seated with new seal under it)?

The rubber line is usually the issue.
