What causes an auto shut off diesel fuel nozzle 1290 to not shut off?
The day before the fuel nozzle shut off perfectly fine automatically. 2 days later the fuel nozzle overfilled a couple fuel tanks. I was wondering what can cause this and how do I go about fixing this? The fuel nozzle is a 1290 auto shut off. Are there any service manual for this specific fuel nozzle.
