Default C6 Fuel pump

What's the cost of a C6 passenger side fuel pump. I see in GM parts $650, and I also see AC DELCO M10057 Original GM part for $154.
What the difference???

Correct. The driver tank has the electric pump that sends fuel to the rail. The passenger tank has a venturi siphon pump that sends fuel to the driver tank. It rarely fails. What is known to fail is the passenger tank fuel level sensor, which is attached to the siphon pump.

Please provide model year and engine when asking questions like this.
