I installed a Stanadyne 5u pre filter last fall per everyone's suggestion. I just changed both filters @10,500 miles. I cut them open and found just what I wanted. The pre filter was completely black with a few rust spots starting. The factory filter was very clean. Just a small band of brown around the end and no rust.
I think the combination probably caught most everything before it hit the injectors. Whew!
By the way, I seem to be a rebel by selecting the stanadyne setup but I am releived now. The modular setup cost a third of the others and is a piece of cake to change. I don't need any tools to change filters and it has a bleeder valve to prime by gravity. It also has a clear water separator that is easy to drain.
Thanks to all.
