[W126 Coupe] Buzzing Fuel Pump

[Terry Ratliff]

I recently bought a spare Bosch fuel pump off eBay for $109 + shipping, tax
for a total of $126. I don't know where the guy steals them from but the
price is right:

Hi Dave,

If you notice the buzz while sitting in the car and it's either 
noticeable for the first time or louder since the fuel filter was 
replaced, it's a good indicator that the pump is at the end of it's 
life.  Time for a new one. I've also just had them start buzzing loudly 
as cold weather has set in.  Again time for a new pump.
