It atomizes and injects fuel into the combustion chamber, a critical function for proper engine performance. Over time, nozzles wear out, causing hard starting, rough idle, power loss, or excessive smoke; replacing them restores fuel efficiency and reliability. It belongs to the 7000 series fuel system and is typically sourced as a remanufactured unit.
