uprated fuel rails

hi guys got a 2002 wrx i have fitted 650cc injectors and tried firing car today but had a monumental fuel leak from the top of an injector where the fuel rail connects would i benefit from having uprated fuel rails or should i be ok if i change the rubber "o" ring

cheers james

Fuel rails still think you should don't need with 650cc,they're OK for 450bhp.
Try replace "O" rings,i bought them from James@Anger and never been used on my build there.

Your Bug Fuel rails are fine unless you are after big figures

Your DENSO ECU will struggle with those injectors without a pretty swift remap, especially if you have changed fuel pump / FPR and upped the pressure......
