[Diy_efi] Leaky fuel rail fiasco

[Gary]

Hold it, hold it!  Don't DRILL ANYTHING.  Has anyone ever looked 
at the wall finish for the injector seating in the fuel rail?  That is NOT
a drilled hole.  That is a high quality reamed hole.  DO it the correct
way,. or put it in the hands of a compeetent machnist.  FFT, and WTTW.
That surface is meant to seal fuel pressure, with the help of an 'O' ring.
