So I was doing some reading and heard from multiple people that the fuel pump in 21+ models seem to run stronger than LT1s prior, I couldn’t find anything using my VIN so I called the dealership and they told me the lowside pump used in the my car was only used from 2021 - 2024.

I have no clue if it’s just the LT4 pump or an upgraded LT1 pump but I think they’d probably save cost just using one pump for all v8 models so I’m hoping it’s just the LT4 pump. I know the 1LES come default with the LT4 pump, mine is a non 1LE and still it’s different from older SS models. I don’t know if anyone’s done any testing on the lowside but I’d love to hear any experiences had.
