Tractor stalls, dies under no load. Have purged fuel lines with exception of the elusive fuel bolt allegedly on the fuel injector assembly. Manual sucks as to location of his bolt. Any help would be appreciated.
I think what you must be talking about is the banjo bolt that attaches the fuel line to the injector pump. I have had a couple of tractors that I had to blow out the fuel lines with an air compressor, and that solved the stalling problem.
I have also had a couple where we had to do the same.
We actually found a little piece of plastic stuck in the fuel line on one of them.
I think it was the plastic from where the tank was punched out for the fuel line.
