Bought some new ones with multiple tips and angles. They are great. BUTTTTTT. Iv got the fuel rail almost completely off and can not get the bolts that attach the black cover over the fuel pressure regulator unbolted from the common chamber. Even PB blaster has not worked yet.

Ill post pics later, if you all do not know what bolts I am talking about. They are completely round and require a large allen wrench. Talk about leverage with an allen wrench.

Has anyone done this repair yet?
