I’ve got a Ford 5000 with the minimec pump and dual fuel filters. Tractor recently started surging and will die. Upon further investigation, I have found that after the engine dies, the second fuel filter (one closest to the injection pump) will not have fuel in it while the first filter will. I can open the bleed screw and work the hand pump and bleeds off just fine, starts up and runs perfect for about a minute then starts to surge and die again. Went through this procedure 3 times and had the same problems. Any ideas?
