Fuel screw question
I know I started a thread on this before, but I can't find it. I just got a pyro for Christmas, so I'm going to turn up the fuel on the truck. I've searched over the web for a procedure and have kinda gotten the gist of the process, but I'm still wondering a couple things:Where to put the probe, How to turn the engine to line up the pump, How much to turn it up, and how much a "Flat" is. I'm a rookie when it comes to this. 
Any pictures will help a lot.

Any pictures will help a lot."Where to put the probe?" - Most accurate will be by back 2 cylinders on drivers side in the manifold but anywhere before the turbo would work.
"How to turn the engine to line up the pump?" - 15/16 (I think) socket on the harmonic balancer and you can turn the engine over slowly to line it up
"How much to turn it up?" Depends a lot on NA vs turbo and EGTs, figuring turbo and no egts problems you can max out the pump and just use smoke as an indication of when to stop turning it up.
"How much is a flat?" - The allen wrench you use to turn it up with will have flat side on it, a flat is turning it enough for the next flat (think 1/8th a turn)

Most likley on an NA youll only be able to get a flat or 2 before you greatly risk melting it down (1100 max EGTs), harmonic balancer is on the front of your crankshaft (below fan/water pump, multiple V belts attached)

I think this shows the best probe location. 1 Flat is 1/6 of a turn, there are 6 flats on an allen wrench.
New Injectors have New Tips, Rebuilt Injector have old tips ...
A Pyrometer measures the Exhaust Gas Temperature (EGT), they are installed in the Exhaust stream as close to the pistons as possible. The Exhaust manifold is the best place.
Like:
See the line bent 90 degrees ... That is my pyro probe installed into the left exhaust manifold collector.
As for Battery Cables, best thing to do is take it to a shop that can build custom cables and have them fab it up.
I did recently find a source of pre-fabbed cables for a good price ... I have to go looking again, I lost it.
-Enjoy

I believe that's the passenger side. Here's the thread I pulled that from: https://www.ford-trucks.com/forums/1...injectors.html
I remember festus' posts a while back on the subject and did an advanced search with his username and a couple keywords. (pyro probe or something)

Depending on what you have for a drill, you may be able to drill the manifold in place. For a NA engine, don't worry about the shavings, they can go straight out the exhaust. For a turbo, take off the crossover pipe and make sure to carefully clean up any shavings inside the pipe after drilling, definitely don't want one going through the turbo.
If you take off the cover on the oil fill you'll be able to see the pump turn as you rotate the engine. I can't quite remember exactly where to turn it too, but I want to say put the locating pin at 12:00 and the fuel screw will line up (I may be totally wrong on that though, so double check it, some where there is a picture posted).

OK. I think I got enough info gathered to do this. I can hopefully do it tomorrow. I'll get a picture of the pyro tomorrow. Any more pics will be helpful. So what's the max EGTs for these diesels?

On the right side of the pump, loosen both screws on the cover (should take 1/4'' wrench) remove only the top one and allow the cover to rotate downward. (fuel will spill out and drain down the right side of the bellhousing) Lay a mirror down by the cover and shine a light at it and rotate the motor until the allen head screw comes into view.
A 5/32'' allen wrench is required make sure its good quality because it takes some force to turn it. I have had good luck sliding a hollow shaft nutdriver over the allen wrench as leverage to turn it.
Rotation to increase fuel is clockwise when viewed for the right fender.
Aluminum melts at 1200*F. These have oil cooled pistons so they can handle more then that. Coming strait from the directions with my Hypermax turbo kit (numbers are good for NA too) is 1300*F intermediate (less then 1 min) and 1100*F sustained EGT's

the correct way to set your fuel is to max gross your setup to the fullest you know you ever will then find a large hill.a hill you know you'll be at max gross and hold her WOT.
watch your EGT's.if they can get out of hand quickly even if dropping a gear doesn't do enough and you need to back off the skinny as well,then you have your fuel turned up way too high.
whatever you do,don't try and max the fuel/boost for when your running empty or your truck will become worthless come work time.

oops.forgot this;i meant edit not reply again.ah well.
"Fuel injection pump adjustment article"
remember read the pyro for a bit first.turn the fuel up (if needed) latter on.don't start by turning the fuel up and hope the egts still remain safe.trying to find out that way,could cost you an engine.
p.s. that's one heck of an xmas gift! congrats!

Hot dog! Thanks man. Ya found the article I lost that talked about this. Yeah, I'll give it a read. I don't need much more power. Just a little more "GO". It will accelerate up the steepest hill we have here.(Screaming thanks to the T19 tranny )
