I have a 1991 420SEL and it kept stalling while driving and in the middle of nowhere. I took it to a mechanic and this mechanic told me that I need two need two new fuel pumps or possibly a relay for the fuel pumps. I purchased two fuel pumps and a new relay - waiting for delivery since I bought them online. He is telling me the labor is about $150 (3-4 hours). Would appreciate if someone can advise if this is accurate.

I could be emailed here .. or at ahyat@sbcglobal.net.

Thanks for all your help.

 

replacing the fuel pumps and filter takes only 0.8 hour. at most including checking and testing, it will take 1.2 hour.

 

it might been correct, but on my 88 560 sel i paid, 356 for the ones on my 88 560 sel....

 

If it's done right, that's not too bad.
