i read that bulletin in my alldata and checked how does the fuel system on that 2008 c5500 6.6l work is it a vaccumn draw?up untill the fuel filter and oil change it ran perfectly. only the service oil wrench light on is there a priming method as there is NO fuel coming out at the lines right at the filter housing when cranking.i found that there isnt a supply pump all depends on the main high pressure pumpand a completely intact system
thanks dave but i went through all that no issues before and no to the adding from an external source i back traced and dug up some more info to find out more on how the system actually works from start to finish.[ like a j.d.tractor]and got it running thanks
