To protect the precision-machined nozzle holes, use clean diesel fuel, replace fuel filters on time, drain the water separator and keep tanks and fuel lines clean. Test the spray pattern after nozzle repair and scan ECM fault codes when performance problems such as hard starting, rough idle, black smoke or power loss appear.
