Tractor Repair: injectors, fuel leaks, injector pump

Question
I recently tried to stop some fuel leaks on my international b414 tractor. While doing this I removed a cover on the side of the injector pump and lost all of the fuel out of the pump. The problem I am having now is that I can't get fuel back to the injectors. Have even pulled tractor around with a chain, but no luck. Any help would be appreciated

Answer
Hello,

  First bleed the filter, and then the fuel supply line up to the injection pump by loosening the fuel line fitting on the pump. Then loosen all of the injection line fittings at the injectors.  Crank the engine at full throttle until fuel squirts out at all the injectors, then tighten the fittings again.
