onan diesel injector 5 sided bolt

[matthews2001]

Hi all trying to fix a leak in my generator at the injector, I know cars pretty well but not diesel, or injectors.

Starting leaking after service from FLEET PRIDE

There are two 5 sided bolts at the injector plate? I think that may be the leak.

Anyone have experience with this? thanks Do I look for a 5 sided wrench? Are they available?

This is a onan 12kw rv/commercial generator

Are Onan cummins generators unusual? Is that why there are no comments?

thanks
