So: for me: parked wife's car. Shut off. She asked me to back up to not be under a tree. Start the car. Put in R. Car stalls.

Long story short; 60 minutes later, her car now has MY fuel pump since hers no longer does. (Pump fuel).

Quick bit of comparison testing indicated when voltage applied on her pump no whir / humm. Mine did so I swapped mine in.

It was a conscious decision that I could have a second x5 for comparing and borrowing parts and this is the third time it's come in handy.
