rubber fuel lines on the fuel returns & the O rings on the injectors , anyone ever had this problem?

that run's from each injector , anyone ever do this? tks in advance

Any wet spots at the oring or cap hose connections.. there is an air intrusion somewhere. Check the filter header too for wet spots.......park the truck nose down and problem will go away.

Never heard how you could remove returns, where is excess diesel fuel going to go. Can't just shut it off at the injector.

Do visit this site for good info............ http://www.intellidog.com/dieselmann/idi2.htm Check out filter header leaks if no visibles on the return system. Remember air will enter where diesel may not escape.
