Fuel Pump on W123 diesel??
Okay, I have been told to look at/replace my Fuel Pump. Not the Injection Pump, but the Fuel Pump. I have very slow acceleration, especially for a turbo. Now, I have been searching and searching and searching for the fuel pump. Looking at NAPA Online, Oreilly's, and other places. I can't find anything. I think I might know what it is on the car, but would like some confirmation. Anyone with pictures?? Thank You for any help!

You don't need a fuel pump.
You need to change your fuel filters and adjust the pressure relief valve spring to 27mm. its extremely rare for the fuel pump to fail, most of the time its only the check valves that need to be cleaned.

It has brand new filters from the Previous owner. I don't know if the pressure relief valve is set right. Do you know where it is?? Sorry, but I am relatively new to all of this.
