But not the separator, Davco or other the lift pump will not fill it, you must fill it will fuel or the truck won’t start! At least that has been my experience. Also if you did put the davco on dry and then cranked it a bit, the air trapped air in the system may take 5 or 6, one minute on, key cycles for the lift pump to purge even after you have filled the davco with fuel. If your tanks are super full pop the fuel caps off when you do your 5 or 6 key cycles for priming.
I agree with the guys above, nothing in the EGR tune up would keep the truck from cranking up even if it was messed up.
Gotta be filter, or something else.
Correct you are. I've got it figured out now. I can look at it now and seem to know how to tackle . Purging the system. Thanks
