What think about jcb excavator? Isuzu engine kawasaki pump model

[@zawmin8602]

4HK1 Isuzu is good engine, using denso fuel parts more stronger than Delphi , especially this suitable for developing country . Original Hydraulic pump KTM use on jcb excavator model 200-260 also good , like Kawasaki , not often happen problem.

Why you changed all the common rail
Why you dont just change the pressure relief vlve ?

Already tried by pressure limiter valve anyway and could not solve mate.
