Sorry to hear the injector went.  As I remember replacing them definitely looked like something one could do oneself - they are high on the engine and are just pressed into little 0-ring like gaskets on the manifold. If this happened to me, and I did the work myself, i would replace all 4 - almost all the labor is in removing and installing the rail, so negligible increment to do all injectors at once. 

Please post here to let us know how it went.

Good luck!

Amazon.com let me down big time.  They promised 2 day delivery on four Motorcraft CM-5148s  then when I went back to check on the status it told me arrival date was Jan 1-Feb 1!    Back-ordered, apparently.

Anyway it all worked out because there are 4 injectors now waiting for me in Bellingham at Walmart. 

 

I watched the youtube video and it looks pretty straightforward.   Stay tuned....

Ok, so have removed the cover and unplugged all the injectors and various sensors around the fuel rail.  Only problem is I can't see a way to easily disconnect the fuel line from the fuel rail.   There is a small metal tube leading from the fuel rail into a bell shaped metal connector.  I don't know if I can just pull the fuel rail out of this bell shaped receptacle or if that will damage anything. 

 

It doesn't appear as if there are any other connections further up the fuel line.

 

Any help appreciated!

 

(UPDATE: )

Figured it out.   It's a push on style fuel connector with four little tabs inside the "bell".   You can get a disconnect tool, but I just took a 3/8" length of PVC tube, cut down the middle.   I jammed it in the bell part with a screwdriver and the two tubes came apart.

 

Job took me about two hours in total.   Removal of the fuel rail, with that rat's maze of cables, was the only daunting part of the job.

 

Speaking of rodents, I needed to vacuum out some droppings from around the top of the cylinder head.  I guess it's pretty cozy under the air cleaner cover when the mercury falls.

 

Car is back to running smoothly.  Incidentally, a Ford dealership in Vancouver wanted to charge me $140 CAD for each injector.  I found them for around $40 USD online out of the States.
