Yes the part was priced a bit on the high side but when I considered the installation procedure. The level of effort to remove and replace the OEM part was so much simpler than reconstructing the entire circuit. I was ready to do that but this was like finding money where time is any consideration.
So far the steel return line to the backhoe loader bucket has been removed cleaned, braised, primed and re installed. The compression fittings were in a tight spot between the frame, took a good deal of the machine apart just to get to it. After braking several tools during the removal process, it is now working perfectly. The hoe section is greased, and today the bucket section and undercarriage will get done. Then the hydraulic cylinders that have gotten to be more than a drip will be taken care of next. The air conditioner for my wife's car has not yet arrived, looking forward to getting that replaced.
So many things to do, that O E M - Gas Tank Selector Valve with Solenoid was a steal at any price. There is a full tank back there about $80.00, I need to use it up.
