  • HPDI fuel injector gasket set versus four stroke engine

    Do HPDI engines use different gasket sets for the injectors compared to four stroke engines? Since the fuel pressures in the HPDI line are over 10 times that of the four stroke engines, it would seem like the gaskets would need to be more robust. If so, would a local injector cleaning shop know this and not put the standard gaskets on after servicing the injectors?

    The gaskets/O rings are different.

    With respect to the HPDI injectors, I doubt a cleaning service is going to be furnishing new gaskets with refurbished HPDI injectors.
