540a won't stay running

[ohiowoodchuck]

transfer pump fuel pressure per jd tech manual 4 to 5 psi. your trouble is most likely. fuel line where it goes into the tank. something floating around in the tank. did you drain the sump in the tank??? rust in it. they used a small steel line that went across the top of the tank then down. that would crack. the easy fix was drill a new hole braze a compression fitting in the tank then use copper tubing. the Ferrell keeps it water tight. like i said before there are check valves and screen in the transfer pump. in order for us to help you we need all the facts. what it did and when. if the return line is restricted it will run poorly or not at all

Thanks for clearing that up. I was way off with my guess.
