Hand pump or gasket under it are notorious for leaking air .
Have had all the other posters things happen in a fleet of 3208s and several other Cats but
most common was had pump leaking air into system.
Had 3176 with same hand pump leak at gasket truck stop when tank was empty after about 10 miles
of course was 60 from home at time.
So I would bet on hand pump first.
Hope this helps

Guys - have a 3208 in a Ford dump truck. Having issues with it staying running. Got it all ready to get DOT inspection Saturday and about 6 miles from home on its way to the shop where we get our inspections done it starts to puke and gag and loses all power... Seems to be getting just enough fuel to barely idle. Let it sit barely idling and then after a bit has enough fuel to rev engine but not hardly enough to move. Pulled it home got in our shop and my dad pumped the hand prime pump a few times while running and that helped it momentarily a lot. We have an electric pump right above tank going to fuel filter housing. I'm suspecting hand pump leaking air? Gonna change fuel filter tomorrow night but the filter on it is was replaced last year and hardly saw any miles. Ideas? Thanks guys.
