and to who it was the one who told me about the keyway, I thank you because majority of the problems with the way my kia was running, that keyway really made a big difference. I fixed it and now it runs great. Thank You.
Did the dealer replace the entire fuel pump assembly, and was it a new unit?
Was the tank a new replacement? I only ask because if both were new, then it should not be a major cost (labor $$$) issue to pull the fuel pump & sender unit quickly to check..
If so, I'd be calling the Service Manager and explain the problem - it should be under warranty.
re: tank pressure sensor, I'd be explaining that to the dealer also. If they have the car back in the shop for the gauge diagnosis, maybe they will work with you on getting that fixed up also.
If no joy from the dealership, then you will need to do some electrical testing at the fuel pump to check voltage -> to see where the issue is, e.g.: the tank level sender, or in the wiring in-between.
(And source a replacement tank pressure sensor from OEM / 3rd-party vendor, or salvage yard..)
To answer your question, yes, there should be (2) plugs back at the tank: (1) for the fuel pump & fuel gauge, (1) for the tank pressure sensor.
