Injector Identification
How do I determine what injectors I have? Many of the parts suppliers list 1999-2002 as the same, yet I hear their are AA, AB, AD, AE, etc. I know that the #8 is supposed to be an AE, but what about the other 7? I have a 2003 7.3. Most of the parts suppliers list a Ford part number that doesn't match the numbers I see others use. For example, 1 injector listed on Ebay as the #8 long lead was #AE1833629C1. That # doesn't correspond to the others, which are Ford typical "F" numbers.

Yes, they all run AD injectors. After 2002 they put an AE in the #8 hole, and some earlier trucks who were diagnosed as having fuel "cackle" might have an AE installed in the #8.

The chart on page four explaines what injectors went in when.

If so, wouldn't I want to swap that out for an AD injector after doing the fuel system mods?

ITP claims that the AE injector with a regulated return system may cause injector knock on the #8 cylinder, and they reccomend you replace it with an AD if you have knock.
The AE injectors give a larger pilot fuel shot, ITP reccomends that you run the AE injector with their regulated return kit unless you have injector knock. I don't think your 01 should have an AE unless the dealer installed one for cackle. If you can get an OAISIS report on your pickup from a dealer you should be able to find out.

Some builders etch what the injector is on the body, but most do not. Chances are you would need to send the to someone like Bitterroot Diesel or Rosewood to have them tested and identified.
