    Pretty sure it was made by caterpillar- it's their heui fuel system- hydraulically actuated electronically controlled unit injectors.

    I'm getting low engine temps, so low that tech 2 won't even start the diagnosis. The mechanic suspects it's caused by faulty injectors due to rough idle too. They can't repair them so may have to replace.

    The injector sleeve O-ring is available here and can be changed if damaged when removing injector.

    the term HEUI appears in the official isuzu thailand website

    ... Control by HEUI (Hydraulic Electric Unit Injector) dispensing fine fuel mist into the combustion chamber with 140 Mpa (1,400 Kg./cm2 ) With High power 5 way Electronic Fuel Injectors

    someone indeed confirmed to me that it is indeed done by caterpillar
