Kukho iindidi ezintathu zombhobho ogcina indongomane yesitofu se-diesel esiveliswe yinkampani ye-YS: i-Bosch yodidi lwe-nozzle cap nuts, i-Denso uhlobo lwe-nozzle cap nuts kunye ne-Carter nozzle cap nuts.
Umzimba wesitofu se-fuel, ibhloko yesikhala yesitofu se-fuel kunye nevalve yenaliti zidityaniswe ziphelele nge-fuel nozzle cap nut.
I-YS yesitofu somlomo wesitofu sokugcina indongomane ithembekile kumgangatho, kulula ukuyifaka, kwaye inkqubo ephuculweyo yemveliso yomlomo wesivalo sentongomane inciphisa iindleko zoqoqosho zabathengi.
