I am not sure of what you are getting at, but i have been watching my average fuel and how many miles left. No according to the manual it states that we have a 26 gallon tank. When i get down to where it is showing that i have 11 miles left. I stopped to fill up and it stopped at 19 gallons, 7 gallons short of what you would think it would take to get close to fill up.
I did the enevitable and sit there and pumped in two more gallons to bring it up to 21 gallons total that i could get into the tank with 11 miles left on the fuel consumption computer that came with the truck. Any ideas??? I know people say just take it out when it shuts off, fuel gets in the evaporator and is lost. Is this true? So far every tank on fill up acts the same way. I got down to 6 miles left on tank and it cut off at 20gallons. Thanks for any ideas you can throw my way..
