Hey everyone!

My mother-in-law's 300E had both fuel pumps replaced about
a year ago at a shop that charged more for the service than
the purchase price of a good used diesel. Anyhow, it has
happened again. I have done some work on the car (brakes,
waterpump, radiator, etc.) but I know more about the good old diesels. How hard is this job? How common is it for them to fail? Are there any external reasons (relays, etc)
for premature failure? Can I just bolt on a racing fuel pump from J.C. Whitney and by-pass the whole thing (Just
kidding!! Maybe....)?

Thanks, sorry for so many questions!

Klaus
