You'd be looking for a 45* feedneck adapter elbow (they only come in straight or 45*) to get the hopper to sit vertical.
You can pick these up at quite a few places.
Here are a few websites that have the feedneck elbows for sale:

Also check out your local paintball shop. They'll most likely have a few on hand since they can break often and will be able to help you if any problems arise.
