I don't want to speak for anyone else, but I don't understand your exact problem. Is it that you want to use the fitting and tube that came with the pump on the pressure side, but mate it with the pump end of your new hose?
Yes, I want to use the fitting and tube that came with the pump because the Hydraulic places in my town find it extremely difficult to find a piece that will work for me.
When I first mocked up the pump, it looked like the tubing would clear no problem, and the house the Hydraulic shop made would fit perfectly. I stupidly didn't mock up the pump in the correct position (where it would be with a belt on it).
