Good morning NormK and thank you for your reply.
Jason is working out bush at the moment, so hoping I can get more information over the weekend. I don't think it was the same hose, so hopefully more details will be available once I catch up with him.
I'm not familiar with Hydraulic systems, but from a few bits of information I have read, and a YouTube on Pump & Wheel Motor replacement, it seems hydraulic oil runs the parts too hot and they burn out, but again, I'm not 100% sure about that.
