1 and 4 injectors are getting very little fuel to them. Bobcat is running on two cylinders. If I bleed 2 or 3 the engine quits running. I'm hoping that lines maybe plugged instead of injector pump going bad. If I unhook the lines and use the hand primer, will I be able to flush the lines. Not sure what else to do. The lines are getting some fuel to them but it is very little. Injectors 2 and 3 are getting plenty of fuel.
