Any pictures of dirty injectors?

Has anyone got any pics of dirty injectors that I can compare my injectors to? I pulled the top one off my 90 last night but didnt disassemble it, it didnt appear too bad on the outside. But that is the outside. Just want to have something to compare to as I am new to this whole ETEC thing.

An injector ihas 2 internal filters. Only the circular one is accessible after removing the outer shell. I can post images in a day or two.

 

It is very important to follow the service manual procedures exactly or have a factory trained technician do the servicing. Read the disclaimer at the bottom of this post.

Thanks, I have taken mine out and sent them to the injector man. I didnt separate them from the housing however. How difficult is it to remove the injector from the housing?

Re: Any pictures of dirty injectors?

It is a fairly tight fit as the orings have to seal pressurized gasoline. There is a special bridge type puller or you can use a slide hammer that is an Evinrude special tool. A seal kit is recommended for any dissassembled injectors that are reassembled.
