Fuel dispenser debugging 3.1 It is absolutely prohibited to debug fuel dispenser using water rather than oil or fuel. Debugging procedure of fuel dispenser A universal inspection should be conducted before first debugging of fuel dispenser, eliminating various elements that affect operation, lead connection in particular. Computer display screen and presetting display should be carefully examined as switching on power, lighter in electric box also being check. Starting up suction pump and open nozzle, carefully examine all connection and sealed jointer face in case of leakage and penetration. Confirming each nozzle is corresponded to its produ fuel dispenser
