Fuel mileage decrease or sensor

[elijah.anderson]

Having trouble with my truck either burning a lot of fuel or not reading correctly. I have had a few people say that its not reading properly because its not the right tank, FYI it used to be a 2.8L V6 and now its a 2.,5L 4cyl. So its a bigger tank than what its used to but I'm not quite cnvinced that its the sensor. Need advice or ideas. Thanks . :MJ 1: .

Try filling the tank and seeing how low it really is?

The size of the motor (even if you change it) has no link to the tank and gauge....if the tank and gauge are the original.....any miss-reading would be related to either the sending unit or the gauge itself.....
