Replaced and refilled both new FFs before attempting to start. C7 ran fine then choppy then shutdown and can't restart. Tried to restart 4 times and almost ran but not starting. Should I use ether ...

From a prior thread (http://www.rv.net/forum/index.cfm/fuseaction/thread/tid/28628438/gotomsg/28628646.cfm#28628646 he has a Caterpillar engine WITH MANUAL PRIMER PUMP.
Assuming he now has fuel in the tank, I would sure start by giving that manual pump 200 or so pumps. If that doesn't prime it because of the 30+ feet of AIR in the fuel line from tank to primary filter, then he will need to pressurize the tank (like to 2 PSI) with someone else cracking open the outlet to the primary filter. When air purged from the line, the manual pump WILL prime it just fine.
Moral of the story, don't run out of diesel-- it is a lot of extra work and is VERY HARD ON THE INJECTION SYSTEM. On all diesels, fuel is used to cool and lubricate the head and injection system. When near the bottom of the tank, the fuel in the tank will be hotter and hotter, as it recirculates. NOT a good idea to run low!
