I just purchased my truck and the shutoff sol. was'nt working. I took the sol. and brackets off the inj. pump and installed a shutoff cable purchased from JD for a 4430 ag. tractor. I mounted the knob end to the rt. of my park brake release lever. I made the bracket that holds the cable housing to the inj. pump and the one that goes on the fuel shutoff arm coming out of the pump. The JD cable has a nice round orange knob that has a fuel pump symbol with a circle and a slash line through it. This repair cost me $60 compared to $200-260. If anyone is interested I could put this in a kit and send it out. And also the plastic ball sockets on my throttle rod were wear out and I was able to buy new ones from JD for $6. 50 ea. 1-rht and 1-lht in metric.
