Injection pump diagram ?

I am looking for a diagram of the injection pump for my 1994 F250 7.3 IDI.

Is there any kind of internal filter or screen which I can check to see if it is clogged ?

Thanks


(I could not find it here when seached and I applogize in advance if it has be been posted . )

There is a filter screen in the nose where the main line comes in the front.

Sent a pic and some other info...... If perhaps there was bio in your fuel and it grew in the IP you may have a plugged inlet filter. Bio when it dies is like the skin on a drowned person.....becomes really white and flakey.
