MPFI v-6 to 350 carb swap question?
 

I am planning to use the factory electric fuel pump and I really need to know what I need to accomplish this for car.
I know I need a regulator and return but which regulator and can you run the return back through factory line?
do you still run the factory fuel filter?
I want to completely remove evap but I can't get a "vented Gas Cap" what are my other options?

The Mallory 4309 is a popular return-style regulator choice. I believe Holley makes one now, too. You can use the factory return line.

You need a filter. Before the reg is a good thing, so the factory filter is simple.

Why do you want to remove evap? It doesn't hurt anything. You could put in a 4th gen fuel tank that has the evap system mounted on the tank. Or, you could vent the tank through a filter on the end of the evap line (fumes may be a problem).

well the area were the evap canister is pretty much rotted away and repairing it as well as the battery box. I just figured that I could just remove it for looks only.
