[Diy_efi] Tapping Metric Injector Threads

[Brian Michalk]

I've got a Bosch CIS injector, 0 437 502 047
It has an M12x1.5 metric thread.  That's 12mm major diameter with 1.5mm
pitch.

I bought a tap from MSC that I thought was supposed to be tapered.  I tapped
some scrap metal, and the injector screws into it with a very loose sloppy
fit.  I will try a smaller drill bit size, but I don't think that's going to
help.

Does anyone know if there exists such a tapered tap, like for NTP, except
metric?

If not, then I'll have to use O-rings.
