Fuel Injector Seals

I could use some help. Sorry if this is already posted here, but a couple searches didn't get me anywhere.

I am getting ready to replace my fuel injectors because I have a leak. The new injectors came with o-rings obviously, but my leak is caused by the larger seals that they are pressed into falling apart. I've been searching google and can't find these things anywhere. Does anyone know where to get replacements? Do I need to take a trip to the dealer?

Have to say I can't ID what you are referring to?

Fuel rail is metal, lower intake is metal, O-ring at each end of injector seals it between the two metal parts.

Is there a bushing or other removable part in the fuel rail?
I haven't run across that before.
It would be a dealer part as far as I can say.

Good read here on changing 4.0l injectors: How To: 4.0 OHV Injector O-Rings - Ford Explorer and Ranger Forums "Serious Explorations"

One other thing, the electrical connectors for the injectors are known to have the tabs break off, they get hard over the years and just snap off.
So have some small zip ties or similar to hold broken connectors to injectors, or get new connectors as needed; loose connector WILL cause misfires

I did find this diagram of fuel rail and injectors: http://ww2.justanswer.com/uploads/Ov..._fuel_rail.gif
Seems to list all the parts

Thanks for the help. I figured it was a dealer item but couldn't figure out what to tell them I needed.

According to the diagram it's a noise isolator.

Here's a couple pics of my broken part:

Fair enough, I thought that just came with new injectors.
