Tractor Repair: Diesel Tractor Ran Out of fuel, injector lines, fuel petcock

Question
Hi there, hope you can help.  My New Holland TC 40D ran out of fuel and now I cannot restart.  I have instructions on how to bleed the lines but have lost my part manual and cannot figure out where to start. Someone else will be doing this for me but they need some instruction on what the fuel petcock looks like, etc. Any help is greatly appreciated. Thanks!

Answer
Hello Shannon,

  Even after filling the tank and getting fuel to the filter and injection pump, there will still be air in the injector lines.  You will need to loosen all the injector line fittings at the injectors, then crank the engine until fuel squirts out at each injector fitting, then tighten them back up, and it will start.  The fuel petcock is what shuts the fuel off at the bottom of the fuel tank, or on the filter base.  I think it is a quarter-turn valve.  As long as nobody turned it to shut the fuel off, you shouldn't need to do anything with it.  Normally, it is only used to shut off the fuel so the tank doesn't drain out while the filter is being changed.

                  Good luck,
