As title states Requesters are not working in AllTheMods 8. I can hook up a regular Requestor from RSRequester mod and it works fine. If I plug in an Elite, Ultra, or Creative Requester and open the interface it says 5000 in the amount to keep in storage. You are unable to change this 5000 and it will not 'request' anything. The example I'll show is crafting a water bucket (my pattern is mystical agriculture craft).

This image is of the requester just placed no changes - see how it is automatically set to 5000

Next image I put a water bucket in and set to 10 to keep on hand

Close and re-opened interface > set back to 5000

Crafting monitor shows nothing being created even though requester has a bucket set to 5000 (since i cant set 10)

Proving I have a water bucket craft available
