alright my friend has one of these sitting at his house has not run in a few years. they kind of parked it on the farm and never got around to using it because they bought a new truck. Are the 6.9s good engines I am going with him to try to get her running this upcoming weekend. What tools will I need to get it going parts? I was thinking a crescent tool set that i have and A battery what else is needed to get an old diesel running?
