    Hello all I have a ‘21 SR5 I have noticed on a couple occasions coming back from the woods and just now, what sounds like a motor running from underneath the truck. I can’t pinpoint exactly, but I think it’s coming from the gas tank. I am wondering if anyone else has experienced this and is this normal, or should I make appt at dealership? I have the long hauler tank (38 gal).
