Tractor Repair: farm pro 20 hp, full stream, fuel flow

Question
I have a a farm pro 20hp that acts like it is not getting fuel. However, I have checked all fuel lines from the tank to the block and the fuel injectors seem to be working. When the tractor starts to smother out I can press the clutch or pump the prime pump and it will pick back up the rpm's. Any suggestions?

Answer
  Hello,

  If it runs better when you pump the primer, it has to be starving for fuel.
  Check the fuel flow right out of the tank.  It has to come out full stream, a little trickle isn't enough.  Change fuel filters and bleed the system if you haven't already done so.
