Hey guys has anyone ever taken the stock fuel rail and drill and tap it with a metric threads so it will fit AN fitting.

How about something like this?
EXTREME PSI : Your #1 Source for In Stock Performance Parts - Fuel Rail Fitting -6AN: Mitsubishi Eclipse 90-94 Turbo

Yes, people have done that before. FFWD does:

That's exactly what I did to mine. Don't buy those expensive adapters unless you plan on going back to stock some day. Tap, install with tephlon sealant and call it good.

Here's some additional information with the Tap sizes people have used and good sealing advice for the fittings.

Ahh I remember coming across that thread when I was searching to tap my rail.

I tapped mine with a 3/8 NPT and used the following NPT > -6AN adapters from summit ith a little ARP thread sealer:
Adapter

Here's an easy way to adapt -6AN to your stock fuel filter to get rid of the banjo bolt and make a nice feed line:
From Summit:
Mikuni Carb Adapter - Replaces Banjo
-6 AN 45* - Then run your braided line to another -6 45* on the inlet of the rail.

You can go a cheaper route and use a NPT to AN 90* adapter on the rail inlet as well, but it really only saves you a couple bucks.

Thanks guys for the help. I ended up just buying two 6an weld ons for like 3 bucks each and took my fuel rail to a local guy and welded the fitting onto the rail for only 10 bucks. so instead of spending 54 or almost 60$ for two little fittings. I paid around 16 dollars. I am like most dsm guys always broke due to having to buy parts after parts .

Nice, I'm actually thinking about taking mine off and having the fittings welded also. Once it's welded you know it will never leak
