So as a few of you know, I am in the process of a low dollar build, nothing fancy. After digging around for various Walbaro 255 or Bosch 044 pumps, I decided to search to see what cars the Bosch 044 pump came on. Low and behold from I can gather it came stock a quite a few cars. The part number for the 044 is 0 580 254 044, which is an external pump.
I search for the part number on this cross reference list and found that the 044 pump has an alternative part number of GCL606 which I found in this cross reference chart:

Shockingly the pump has been found in various Porsches, Afla Ramero, Peugot's. The find is that they also came in Volvo's that came in the 2.0/2.3 Turbo engines. I found the complete list of vehicles that came with the GLC606 through this link:

I found a salvage yard that specializes in Volvos and offers 100 day warranty for their parts and I have one shipped to my door for $50. I am keeping the car N/A for the time being and that will give me plenty of time to piss around with cheaper fuel pumps. It's a normal thing for the 700 series volvos to have 200-300k mileage.
I may have stumbled on a way to save some while keeping genuine German part quality. As I find out more, I will post what I find.
