I just talked to the parts dept. at Ford for injector prices and they have a different part number for the #8 injector and it is $40.00 more. Has anyone else heard of this? I have never seen any threads on it here before.

P.S. they are really high on their prices even going through my fathers garage and getting %20 off

 

It's also called a "long Lead" injector. It's supposed to help cure the cackle issue.

 

They used a different injector in # 8 to try and make the engine quieter. As for obtaining stock parts, chcek with an International Truck dealer, Alliant Power, Ebay or do an internet search for injectors. I would not buy them from Ford at their prices.

 

Alliant or Midwest Fuel Injection are among the cheapest I've seen.

 

The long lead injector in the 00 and 01 trucks is a split shot injector. Your OBS trucks already have a full flow return and have no need for a different injector in the #8 hole.

I think the parts guy was quoting you a part from the wrong year.

 

That could be, he also thought that $12.00 was a lot of money for a set of injector o-rings for all 8 injectors? I informed him that that was for 1 injector.
Ended up buying o ring sets from Southwest Diesel for $7.24 per set
And IPR seal kit for $11.04
Cheaper than anything I found on E-Bay
