I have a 1997 7.3 with around 250K miles on it. I recently installed new injectors and a new map sensor but the fuel bowl has run almost empty twice now and the truck acts like its out of fuel and dies slowly and wont start until I poor more diesel into the fuel bowl and prime it. it runs ok for a while after that, besides misfiring at high RPMs, until the fuel bowl goes empty again. There's a pretty steady leak when the truck is running but it goes away after I turn it off. The truck has been misfiring a little at high RPMs for as long as I've had it too. I'm wondering if my fuel bowl has a leak in one of the O-rings or if its one of my fuel lines. Any help would be appreciated, thanks.
