does this part come with a mounting plate for a gx390 13.0?

Answer
Yes, this pump would mount to a Honda GX390. However, this is a bare pump and does not come with any of the fittings or a thermal relief valve. I would recommend going with the fully plumed version of this pump. It will come with everything needed on the pump. I have attached a link for you to view that item.

Answer
I would recommend sticking with the CAT pump. I would go with model SLP67DX39-930. This pump is the fully plumed version of the 67DX and is the same pump. CAT in my opinion makes the best pumps in the industry. I have attached a link for you to view that pump.
