would like ask if any you know problem with it.. My 6.5l will be hard get running.. I have to fill gas on towel and cover turbo hose it will get running but it smooth also sometime has little shake like choke then smooth again all same and when rev it up will be grey smoke and little choke when slow rev it up.. i not sure if it Injections or PMD or else please tell me what is? Thank you!

 

Sounds like you have a problem with a fuel leak from the filter housing combined with faulty lift pump operation?

Do a search on google for "6.5 diesel lift pump test".
Perform the test and report back for further diagnosis.

 

to test the lift pump just hook it straight to battery, mine was giving me trouble and thats how i checked. if it worksyou will hear it. if it doesnt you cant.
