You are correct about the hose from JD. The original hose was smaller dia but rubber. When I removed the return assy, the hoses were soft and slid off the nipples without depressing the clamps. When I picked up the parts, I asked for the correct clamps and was told "those are special order".
The o rings in the breakdown are seals for the injector nozzles. The copper washers sean the nozzles to the injector. I might have been able to replace the injector hoses without removing the return assy but I was not positive that it was only the hoses between the injectors.
The R&R on the return assy requires the steel injector lines be removed. Much larger job. Installing the o rings on the injectors required finding and cutting a thin plastic tube to go over the injector threads to protect the o rings from damage while sliding then down to the grove.
Because of the years I have owned the tractor, I replaced all the fuel lines. As I was putting everything back together, I thought back to when the problem started. I keep the fuel tank full all the time. I had topped off the tank the day before. I removed the fuel cap and could hear the poppet in the cap when I turned it over. I put an air nozzle to the inside and as I blew air into the inner vent hole, nothing came out the top. As I increased the pressure, the vent cleared. I think this might have been a factor in the problem. The engine runs again and no fuel leaks.
Thanks for all of the insight. Diesels were never my forte when I was in business. You are never to old to learn. Ray
