FallenAngelHIM said:okay, for example, if i have I/H/E and want to dump in more fuel to better mix with the increased air flow. i'll throw in a nitroux oxide system. a VAFC. i'll get fuel regulator, fuel rails, fuel filter, and then fuel injectors. that's my example of what i mean.
i'm speaking of the actual size for fitting an AEM aftermarket replacement fuel rail. i hope this makes sense.
