Thanks Jim The job went very well,I changed the 4 rubber T joints but I had difficulty with the O clamps which are not well placed.I also changed the return line.The old one was melted shut,it must have touched the block or the exhaust.I ran the dozer and there were no leaks. Thanks again Bearchopper

Thank you Jim I ordered the Tees I need also the connections so I hope to do the job this weekend.I know what to expect. Thanks again Jim I will let you know how the job goes Bearchopper

Jim you were right the 4th Tee had a fuel line attached to it and appears to be made of a hard plastic tubing of 1/4 in which had melted closed and is connected to the fuel tank.I would like to know if I cut this fuel return line will the fuel rush out before I connect a metal 1/4 metal fuel line to...

I will check the starter and the alternator and see if they are 12v Thanks Jim B Bearchopper

My JD450 has an open and close switch and a start button,I want to keep the start button but install an ignition switch with a key,do I need a switch 24volt because I have 2 12volt batteries or will a 12volt do the job Thanks Bearchopper
