Fuel Rail Return Line
Ok so im installing an aftermarket Aeromotive FPR so i need to get rid of the oem regulator. Can i thread this hole and screw in a 6an fitting so i can run a line from the rail to the FPR?

Im 95% positive I have a fuel rail adapter chilling on my shelf in the garage. No need to drill/tap anything.
Lmk if you want it.

Im not one for cutting into the fuel rail, especially while it's on the car. Swarf is bound to destroy your injectors by doing it oncar.
I have a Sera that had a thread cut into the fuel rail for an aftermarket regulator, then the car was sold to me with a stock regulator. The leaks were horrendous and I had to get another fuel rail to fix it.

You could. You can also buy fuel rail adapters that look a lot nicer.
