Arrow W108 Fuel Pump FS


I recently changed out my fuel pump for a new one

The one in my car was still fully functional, and never gave me any issues besides the fact that it hummed.

I was told by Stuttgart Autohaus in Arizona (who i bought the car from) that sometimes they are noisy and it doesn't necessarily mean that the pump is bad. For piece of mind i switched it out because i got a great deal on a new one.

Pump is sold as is, i pulled it yesterday out of my running 108, but again it does hum. i'm not sure if someone may be interested in rebuilding it, or someone out there just needs something for the time being.

Pulled from a 1972 280SEL 4.5
Bosch Part # 0580 464 125

Asking $100 + Shipping/Paypal

W211 '03 E320 | W108 '72 280SEL 4.5

Swap the "+" and "-" minus leads, run it in reverse for a few minutes using kerosene or diesel fuel as a fluid medium to see if the "humming" goes away.

this pump fits 1976 on cars , it will work on a 108 after modification , the hum could be caused by lack of insulation . new ones made is us are cheap .
