Setting the computer for 34 gallon tank.
I didn't think this would bug me but... I replaced my 26 gallon tank with a 34 gallon tank when the 26G was punctured. I did not replace the sender (add another $500 to do it). The sender I have works fine except for the gauge reading. I could put up with just the computer being off but the fuel gauge also reads empty when I have over gallons left. The computer reads 0 miles to empty when I can drive another 100 miles.
Has anyone heard of being able to adjust the on-board computer by programming it (as it relates to this particlar subject)?

When my fuel gauge on another vehicle was broke I just went by mileage. Not the answer you were wanting, I know, but that is what I'd do.
Is the sender at xx height on the 26 and at a different height on the 34? Not really familiar with the set up. Perhaps you can get one out of a wrecked truck with the 34. Good luck.

RE: Setting the computer for 34 gallon tank.
I'm using mileage now in concert with the MPG on the computer and it's effective. But my wife freaks a bit when she drives it and it's been on empty for 50 miles.
My understanding of the sending unit/fuel pump is that it is a type of accordion system that has the ability to stretch and shrink depending on what it is used in. The two tanks (26 vs. 34) have the exact same height for the sender installation. The difference is the length of the tank. So my thinking is that the computer communicates with the gauge on the amount of fuel; otherwise it should be reading closer to what's in the tank. That's why I asked the question about the computer - I may be wrong - I have been once or twice before.
