Tell me about injector #8

[SonnyStreke]

I have been told this injector differs than the rest in the 7.3, is this correct and what is the reasoning? If this one goes bad does it affect the engine more so than lets say #6? If so how? Thanks for letting me pick your brains

What year is your 7.3?

#8 is a different injector to prevent noise. The noise is commonly referred to as "cackle"..... It fires differently to prevent that.....

It seems #8 does fail more than any othere single injector from what ive seen......but it doesnt affect the running of the motor any differently than any other injector if it fails...

My truck is a 2000 F350 psd.

So this "cackle" injector doesn't cause any different effect than the others if it's bad?

I noticed the cost is higher for the #8, unless I'm just not looking in the right place. I came across a site somewhere selling an entire set of 8 for a really low price (comparably speaking). How would I know if in fact they are selling with the "different" #8 in the set?

Can you place a "regular" injector there? I'm all about saving money where I can but don't want to sacrifice the integrity of the engine either. Truck is all stock to my knowledge.

Yes, you can put a regular one in there.

I suggest a regulated return to fix the cackle issue.

The number 8 injector will be labeled LL (Long Lead) which is the updated injector to correct the cackle.

Wow, you lost me on that one, you're talking to a girl here ;-) I am trying to gain as much knowledge as possible as to not get "taken". The shop tried that on me once already but I was prepared enough to stop them in their tracks, needless to say they did NOT like that.

So back to the point, can replace with regular one but would advise a "regulated return" (I'll get educated on that) would it just be more cost effective to go with the "cackle"?


Thanks for all your help everyone!

You can put a regular injector in the #8 cylinder. There is a possibility that it will cause more "cackle."

A regulated return.

In fact, this is straight from ITP's site.

I recommend the itp setup over others. Wasn't too bad of an install.
