Is there any benefit to adding a fuel rail.

 

the only reason to use a regulator imo is to add an aftermarket regulator, or if you upgrade the feed line and need the rail to match.

 

you wont need a fuel rail until your pushing 450+,the OE is fine. You just cant add more fuel and think that will create more power. An adjustable fuel pressure reg adjusts fuel to your application. But if your still stock, you wont see any gains.

 

The only benefit an aftermarket fuel rail has for low hp applications is looking great.

 

I have seen 600+whp on stock fuel lines and stock fuel rail. lol.
