I worked at a gas station about 20 years ago, so things may have changed since then. When our pumps started running slow, it was almost always due to the pump filters nearing their end of life. They would get clogged with the minerals and sediments in the tank.
I used the super hot infrared burner to get a good sear, then flipped every minute or so while basting with butter. Then pulled it and let it rest for like 7 minutes.
