More likely than not they will have the primary and not the secondarys in stock. I personally woudn't run it without all the filters in place but thats your call. The o rings are prob OK for another go just check em real well before you take off on a drive. The gov is built into the IP, its not an external gadget you can really see, honestly i haven't ever had to mess with one, nor have i read of anyone that has. Now on to the controversial question, the compensator...... for the most part i think 90% of the site agrees that you DO NOT need it hooked up to run anything you damn well please for fuel. The other 10% is off in bizarro world IMO, the truck will run fine with filtered ATF. The only difference will be in power, the compensator kept power constant by adjusting how much is injected into the cyl every time it fires. You are doing the same exact thing with your right foot. All i'm saying is that it may take more or less petal to get the same power depending on your fuel mix. Thats really all it does, no more no less. 2 parts ATF to 1 part diesel ought work fine, but just remember that if you turn the fuel up at all ATF burns hotter then diesel. Don't want to see you cook something inadvertantly. Before messing with the fuel setting it is widely advised to install a pyrometer. Oh, one last thing. You have checked the copper fuel line where it crosses the front frame member , right??? By virtue of its location is seems to get squashed flat and impedes fuel flow bigtime.
