Truck dies at 1/4 tank of fuel
Hi everyone. So i have an issue of my truck dying when the fuel tank just reaches 1/4 tank. At first, i hadnt put that fact together yet, and i was looking at fuel lines and the filter housing for leaks. When i filled the tank, it had no issues and ran perfectly.....until it hit 1/4 tank again, then it just drops off like its out of fuel. I pulled the tank to see if the sending unit had a crack in the pick up yube, but it looked fine. Could the Cp3 pump cause this, like maybe getting weak? I should also add that this is a totally stock truck with no tuner. Tia for any suggestions or advice.
03 Chevy Silverado 2500 HD 4x4 bone stock.
Just trying to have fun till I die!!
