I have raised this before, but I cannot find anywhere on the web where there is a significant explanation and solution of the hesitation I am getting under light throttle, even though it doesn't do it all the time. New in line and fuel filter installed and zero leaks. New air cleaner and all areas cleaned. Small amount of diesel fuel leaking from a couple of the small rubber pipes connecting each injector and returning back to fuel filter housing. What could cause the hesitation at lowish RPM?

Also, anyone know how to make the techometer work on the diesl?

Appreciate any ideas? So far cleaning the old oil off and putting on a new radio antenna has been my limited effort, but clean fuel line is a start. Should I use a fuel additive to clean injectors etc., if so what's recommended?
