What is your question?
Some fuel pumps have a Y in the serial number and priced around $300, some have a W in the serial number and are priced around $800. so what's the difference between the pump with the Y and the one with a W that makes the price change so much??

Hello, which engine do you have in your Tundra? I've looked in the parts information with the OEM catalog as well as an aftermarket website, and it's pretty straightforward as far as I can see to get a proper pump for your vehicle. The next question is: Why are you seeking to replace your pump? You've checked base fuel pressure and it is insufficient?
