It's quite rare to get an aftermarket focuser designed for a round solid tube telescope that fits perfectly. This isn't an issue in any way.
I assume the issue with the small diameter tube is the plate section where the screw holes are on the focuser sits out from the tube ?
Use some neoprene or steel washers to pack out where the screw holes are and then use some slightly longer countersunk head machine screws to attach the focuser.
Collimate the focuser properly on the telescope and then run some black foam weatherstripping material around the edge of the focuser to block the stray light.
