hi
Ive tuned many turbo/na cars over the years and as a part of that has normally always started with replacing a 10+ year old fuel pump as once tuning begins they can tend to underperform or fail completely etc etc, anyway this doesn't appear to be common practice for 350z's I wondered if there is any real reason why this doesn't happen ?, as common sense is telling me to replace my 14 year old fuel pump before I go much further with my build.
I'm lead to believe it isn't the easiest job in the world but is this the only reason ?
any advice welcomed guys
