Was the original return hose (3A713)one or two pieces. It looks like two pieces in the master parts manual. Whats left of the original looks like one piece with a crimped fitting and tube that goes into the control valve and the other end mounts to the pump with a hose clamp. I ordered a set from Blue Dot specialties and the return appears to be two pieces. The lower hose appears to go from the valve to the rubber insulator. It looks I need the second hose from there to the pump which takes a hose clamp on each end. The master parts manual refers to this part as 3A005. I have not seen this part in any of my catalogues will any rubber hose work or is this line under pressue also. NPD shows a one piece unit as their best reproduction and a two piece as a good repro. Any help would be greatly appreciated this system seams like alot of messy engineering.
