rough idle and fuel problem
I have a 99 7.3 PSD, my poblem is that all of a sudden it is running very rough and when i open the valve on my fuel bowl i runs good again. I checked my fuel filter cleaned it and replaced it a then know when i open the valve at the fuel bowl fuel gushes out very fast not like before it was slow and now it flows very very fast. It idles so bad at times it knocks loud. Then it goes to normal.

If you want to clear up the problem once and for all, I did this exact same thing to my '99.

Hi I think I have the same problem. Did this happen after driving it for a while? It seems to do this at stops and while im in reverse. I appreciate the detail you have given. We have been stumped on this for a while. thanks again anna in so cal

Also and this is to all who have done the Hutch mod: I have found that when the tank is less than 1/4 full it's still gulping lots of air as the fuel sloshes around. Makes the truck rock and roll at idle for a few minutes. As time goes by and the fuel settles in the tank and begins to draw pure liquid fuel it settles down. Go fill it up and then it's smooth all the time. So I have made it a habit to start looking for a fuel station at 1/4 to 1/3 tank. By then it's time to pull over anyway. Aching buns and all.
