    Hitachi EX120-2 fuel issue after clean clogged banjo screen filter

    To the above about hp. It won’t run more than 10 seconds. I’ll try to pull the banjo above. Per a diesel mechanic, possible it needs a prime and crack each injector to clear air out.

    Hitachi EX120-2 tack adjuster leaking on zerk fitting side

It's leaking at the joint I guess where the nut 06 screws onto 01, if that makes sense...

    Hitachi EX120-2 tack adjuster leaking on zerk fitting side

    This labeled as 06 is the "Nut" that can be removed and purchased to keep grease in? Would this not let spring loose? So I may need to put in a vice or a way to keep spring from uncoiling etc.
