07 e350 with 104k miles - Fuel Pump Reasonable to go out?

[cmaxwell]

Hi all... I hate these situations. I'm new to LA and don't have a mechanic lined up yet. Of course, the car died in traffic - acting like it ran out of fuel, but the tank is half full.

I had it towed to an independent with "decent" reviews on Yelp. He's telling me the fuel pump is out, $650 to replace.

Questions:

1) Is it reasonable for the fuel pump to go out on this car at 104k miles? I really thought he was going to come back and tell me it was the crank shaft sensor.

2) Is $650 reasonable for this repair in the SoCal area?

3) Anything to ask or confirm before letting them go ahead with the repair?

Thanks everyone!
