Last couple times I've drove mine after about 5-8 minutes it sputters/dies but then starts back up. Today it did it and gas gauge went from half tank to 1/8 tank when it did it and after checking mileage 1/8 tank seemed right. I'm thinking fuel pump is about to go out. Yall agree or?
I would suggest making a separate post for this. That being said, I don’t think a bad fuel pump would cause your fuel gauge to act wacky like that. The pump and the fuel level sensor could have a shared connector that is loose or harness shorting to them both. Are you getting a check engine light? Another possibility is bad evap canister creating vacuum in the gas tank and starving the engine of fuel. I will admit that I have not ever pulled the pump out on my truck, so maybe there is something about that assembly that I am missing.
