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.

ok mate will whip them out tomororo and try replaving them hopefully will be ok

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......
