Hi Thank you for this
I am going to OPt-out , send back to the

sorry I could not help
I had a similar problem on a machine once. Traced it to a failed diaphragm in the fuel aneroid valve.
This has a line from the turbo to the back of the injection pump. If Diaphragm fails, turbo boost pressure can enter the fuel system and then cause pressure in the tank.
(High pressure in the tank can act like "vapor lock". My machine just blew fuel everywhere.)
I will OPT-OUT too as I am not sure this is your issue.
Hello, on these engine it is due to combustion gases going into the fuel rail. Most of the time it is the copper o ring on the bottom of the injector that fails. Where I would start is by replacing all of the injector o rings and retesting. This will eliminate the compression gases going into the fuel system.
Did the concern happen before or after the injectors were replaced?
