Broke one of the tiny bolts (about an M4 or #6) holding down the FPR. I can drill it out, fill and re-tap the hole, but can't for the life of me figure the thread size. M4-.7 seems too big, and #6-32 too coarse (plus I'm thinking it should be metric.)

Any takers?

My suggestion is to just pick up a used fuel block with the regulator on it. We have a few in the garage that can be used. Price is right. PM if interested.
