The third sensor that the new one doesnt have is the pressure sensor, its not used by the truck and was prone to leaking so the newer bases didnt have it.
Now that you have the new base installed, you need to do a complete air bleed procedure.
First disconnect the pink wire from the injector pump, then open the bleeder on the filter base and crank(in short bursts, letting the starter cool in between) untill you get no more air bubbles coming out with the fuel. (A piece of clear plastic hose attached to the bleeder can help avoid a huge mess).
Once that is bled, re-attach the pink wire. Now i want you to crack the injector lines loose at each injector (just break them free and loosen a little bit, dont take them off.)
Again you will be cranking in short bursts (allowing the starter to cool down, and you will probably have to charge the batteries back up.) you will probably want a buddy for this part, you need to watch the lines while he/she cranks the engine. When you see fuel seeping from a particular injector line stop cranking and tighten it down. Repeat until you have fuel at all of the lines.
Then I want you to remove the two small wires from the glow plug relay on the firewall (so the glow plugs cant activate.) and also remove the air filter pan from the top of the engine. Clear the engine bay of any rags or things that could get sucked into the engine. Get a can of ether (listen carefully to this next part) and spray 1second into each side of the intake and then crank the engine.
Its going to fire from the ether, you may have to give it some pedal to keep the engine running (will still have some air in the lines) but dont rev the piss outta it. Keep the rpm's as low as you can while still having the engine running smoothly. Once its running let it run for at least 15minutes to purge any remaining air from the fuel system.
