Hi Tony, bumping this thread for you.
Sounds to me like you have a DE filter.
The best thing you can do right now is take and post lots of pics, pics of each piece of equipment and the various parts, so that we can help you identify everything. Upload them to Photobucket.com and copy and paste the IMG code to each picture, paste them here on your thread and the pics will appear. Then we can help you figure things out.
Sorry about your loss.

But brighter days ahead for you I hope - especially if we can help you get this up and running.
