8.3 250 cummins mods

I have the same thing in my utility truck and I bumped it up a bit. I slid the fuel plate and then fine tuned withthe star wheel... there are good instructions floating around here on how to do it. The pump is the same p-pump that is on the 2nd gen 12v 5.9. You can do all the same pump mods that you can on the 5.9, but I wouldnt get too nuts due to the rest of the drivetrain. Let me know and I can give you some more tips on it.
