Hey guys question for you? I have a 2019 ram 1500 with a 5.7l. It had the 24 gallon tank and I swapped it for the factory 33 gallon tank. Fuel pump and sender is the same part number for both so I used the old pump. When I fill up truck now the range till empty says around 350 which is what is said before and the gas needle works but only for around 350miles then the low fuel light comes on. When I go to fill it up in only takes about 20 gallons so I know there’s more in the tank. Any idea how to relearn the truck ecu or program it? Thanks.
