if i weren't going turbo is it still considered an upgrade to the cars performance, like will i benefit from buying a Walbro or Bosch fuel pump, I have a 98 c230 and my pump went as well, are you changing it yourself? do you know any DIY of this job? sorry to bombard your thread man, im just debating if i should do it myself or tell the my local Mercedes mechanic to do it, (not the stealership) although his labor is not..what we would call cheap neither, but i guess fair, anything would help thanks
