When using a pencil glow plug reamer, this modified 12 mm wrench will allow you to PUSH in on the reamer while turning - and let me tell you - this is needed when you have heavy carbon buildup in the prechambers.
This is something many owner's and mechanics miss. That little check valve on the side of the injection pump can cause a lot of starting problems on the older diesels.
