Just bought a 2001 Tundra 4X4 (4.7 liter, automatic) in Columbus OH, and drove it back to Tucson AZ. I like it. However, the specs (google and the dealer) say that it has a 26.4 gallon tank. Twice on the way back, the gauge was reading about as empty as it could get, and I was only able to get about 21 gallons in it. Was there a smaller tank put in some of them, or is my gas gauge lying to me?
