Injection Nozzles

Each engine cylinder combustion chamber is equipped with one injection nozzle. The injection nozzle has a single fuel inlet fitting and 2 fuel return fittings (one on each side of fuel inlet fitting). The nozzle is threaded into the cylinder head. Injection nozzles are spring loaded and calibrated to open at a specified fuel line pressure. The combustion chamber end of the nozzle has a replaceable compression seal and carbon stop seal.

NOTE: Injection nozzles used in "G" models are shorter than ones used in all other models. Use of incorrect nozzles will damage cylinder heads.
