Fuel life warning after 500 km

I have a 2015 Chevy 2500hd duramax. The fuel filter life was at 0. Change the fuel filter and the Fass fuel filters. Drove about 500 km and the fuel filter life warning back at 0%. Truck is deleted and EGR delete. Cp3 conversion and fass fuel 95 gph. It has a 90 HP tune. Any ideas?

There is a sensor upstream of the factory fuel filter that deals with fuel life. I think there are a couple theads showing the location.

Well I brought it back to the shop where I got the deletes done and it turned out to be 2 things. I have a pin hole leak in a factory fuel line in the valley and their is a frost plug on the cp3 that was leaking. All fixed and pulls hard now.
