Hey Lee, updated info..

After talking with the tech at the injector shop, he had some ideas about your knock.
Since its isolated to number one and you mentioned someone removing the element and putting it back in on number one...I am thinking that it is timed way wrong (each cylinder can be timed individually)
What he said to do was make a scribe mark on the body and on the top element part (the part that is held in by the two nuts.
Those units can rotate in their housings so what you want to do is adjust it, and I quote, "half a hair" one way or the other and see if the noise gets worse or better.
Re-tighten and then give it a shot and see if the noise is worse or better. Depending, continue the adjustment.
This is the do-it-yourself way of adjusting the timing of the elements and it doesn't sound like you can make your knock any worse at this point.

He suggested leaving the nuts sorta tight and then tapping lightly with a hammer to adjust and get that hair-thin movement. Be careful not to mess up any of the others. The more theere are...the harder it is to do.

See how this works for you. Here is a digram to help.

Eureka, Viola,Yippee,Yahoo, etc. The knock went away, but I had to move the top plate counterclockwise between 1/32 and 1/16 inch from scribe mark. Naturally (Murphy's Law) I went the wrong way the first time and it got worse. Thanks ever so much Brandon. I might just be masking over the real problem and time will tell, but for now I'm extremely happy. One note-I had to loosen the injection pipe on the pump to get the plate to move far enough. Glad I procrastinated long enough. Fools rush in where angels fear to tread.
