Thanks
for all of the input. I had already decided I had to remake the fuel
rail. I measured the holes, and there wasn't enough material there to do
anything with.
I had
ordered some more extruded aluminum fuel rail, and this morning I ordered a
.4355 reamer, and a 27/64" (.421875) drill bit from Rutland supply.
Since
I have the old fuel rail in hand, making the new one should be pretty
easy. I bought a long enough piece of fuel rail to make 2, just in
case.

Probably no need to make a new rail
anyway. One of the first
"tricks" I was taught in Machine Tool 101
(36 years ago) was how
to repair a mis-placed hole. I still have
that machinist's clamp and
it's still hard to see the repair.
If the hole is too large to smooth out, it can be drilled out to the
next
size for a pipe thread and tapped. Make a plug with the outside
threaded to match. Screw it in until it won't go anymore (with
reasonable torque.) Mill (or file) flush. [If you really want
it to look
spiffy, chamfer the hole, and mill the installed plug to about
.010"
high of flush, then peen the edges of the plug into the chamfer;
then
mill flush.] Drill new hole and ream to correct size.
Of course - depending on the complexity of the rail - it might still
be easier to make a new one than fix two holes.
Best
