Whatever size bolt came out of the hole will be the size and most rx7 thread pitch is 1.5 or 1.0

You can get a metric thread pitch gauge at Sears or just about anywhere else.

All of the fittings' sizes and pitches of all of the fuel components used on my twin Walbro setup -- attached in the file. Have fun.
