If you want to remove the pump to check or replace, you'll need to lay underneath at the drivers side and look up near the fuel/water separator filter. There is a wiring harness zip tied together shown here. (On mine at least.) You disconnect the lighter grey wiring connector. Pretty easy to trace back if needed or if they changed the color of the connector.
Then I disconnected this hose at the return line Tee. Kind of goes over the top of the pump and is just in the way of work and getting the pump out.
In this photo, I'm pushing the return line hose out of the way with my index finger and pointing to the black plastic mounting nut you have to remove to remove the pump.
I've rotated the pump a little bit clockwise for a better view and to get something on that nut. Doesn't hurt anything. Just a compression connection with an o-ring underneath.
I then took a long screwdriver and bumped the nut counterclockwise to get it loose. I can't think of and/or don't have another tool to do it a better way. Open to suggestions though. Note it is a threaded connection. Not a "turn to lock" connection.
