Injector Removal

I have a 99 f250 with a 7.3 PS. I have over 200,00 miles on her and I was thinking about changing injectors and glow plugs. How hard are the injectors to pull out and do I need any special wrenches to finish the job? What should I be looking for while I'm under there as well? If anyone has any removal tips that would be great.
Thanks

Are you thinking of changing them just because you are afraid they are getting old? Find a mechanic buddy with an enhanced OBDII scanner (alot use Autoenginuity) and they can check the injectors. If you want to change them out, You can get stage one singleshot injectors for $625, less than the cost of some stock injectors. Plus with the tuning you need to run them, youll be around $1000.

Thanks everyone. I had my truck on a scanner recently and it came up with a code for #8 injector. I can't remember what it was but with the amount of miles I thought it is probably time to change. I also am starting to hear a faint miss as well. Probably from #8.

#8 is usually the LL injector which is there to help with fuel starvation in the dead-head fuel system design. The CCK helps with that, so if I were sinking the cabbage into new injectors, I'd think seriously about doing the fuel system mods (CCK or Reg Return, and Hutch) to keep the new injectors happy. BTW, if you do get new ones, I'd like to yank my LL #8 for a standard one -- lemme know if you (or anyone else!!) would like to part with one. I listened to a truck yesterday with a standard #8 and I since then mine's been driving me NUTZ (I know, short drive!!). It sounds like someone hitting the block with a ball-pein hammer!!

Not oil, fuel. And it was done because #6 and #8 fire very close in time and are right next to each other. It was Ford's way of attempting to "fix" it. If you look up the CCK, Regulated return, or Dan's (kwikkordead) fix, you'll see. Basically, they have the fuel feeding the filter/water separator on the top of the engine, then on to the heads which is fine. But they tied the return line into the fuel bowl instead of from each fuel rail off the heads. So what that means is that the heads are a "dead end" for the fuel system. It also means that 6 & 8 are fighting for their fuel at the very end of the system and any air that makes it past the filter bowl MUST go through the injectors -- that's bad. Air = no lubrication, which = extra wear on the injectors.

Hope that helps explain it!

What started it all for me was I was reading about diesel cackle. I found out how the system was designed and was surprised at how many shortcomings were designed right into the fuel supply system.
I know Bosch fuel injection inside and out and I drew on that knowledge.

And if you have the time, energy, and facilities, skip all that and do this to your truck.
It's the best solution overall.
