The X5 left me stranded. Fuel Pump?

[Auto Parts Guy]

So I'm driving home yesterday after work, about 3 miles from home and she just lost power. I coasted into a neighborhood and would crank barely but then die. Tried a few more times and wouldnt start. Had classic fuel pump symptoms. My scanner shows code 8D (P0461 I think in the generic world), which is fuel level circuit A. Although I have no fuel level symptoms. At first i was thinking the break down and code are related, but now I'm not. Thoughts? No other codes or symptoms.

Of course after a buddy towed me home, she crunk right up and I drove into the shop. I did some tests last night and no glaring issue now. Although the fuel pump sounds pretty weak for what thats worth. I hate to throw parts at it but sure does seem like the pump. Are there any cheaper alternatives besides the Delphi pump assembly for $268 at FCP and $177 at Rock Auto? Unless i can find just the Pierburg or TI pump for much cheaper, not looking to save $5 for just the pump. They seem to be in the $120+ range and not offered at FCP. Car has 187k miles.
