PO463 fuel level code after pump install

Hi I had the MMX/Fore single fuel pump installed not too long and my fuel gauge only reads 1/4 to 1/2 full when it's full and I got a PO463 fuel level sensor code. Someone suggested that the pick up wires may have crossed and the leads may need flipping or I may need a new leveling sensor. If I need a new sensor would I be able to get one of a used 2.7, 3.5 fuel pump? Or must it be from a 5.7 or 6.1/6.4 fuel pump?

I haven't taken it back to the shop but that's what I'm thinking it maybe. Would I be able to get the float off a stock pump?

The float module does indeed come off the stock pump. I recently had the same issue and took it apart to find that the way I had wiring it had physically restricted the movement of the float.

Thanks for the information! This was the pump on the left/driver side?
