i read somewhere that you need to learn what is the fuel pressure to determine if is necessary to replace the filter.
also found this thread, where they are discussing something about the pressure, but is too sophisticated for me, and i wonder if the pressures mentioned on the posts 1 and 2 are what we need.
i hope some1 could bring light on it.
