Fuel Capacity?

I have a 2000 EB Expy, 5.4L, 4x4 that is supposed to have a 30 gallon fuel tank. I can never squeeze much more than 27 gallons into it (and that's after running it 40 miles past 0 miles to empty on the trip computer and the fuel needle is more than a full needle below E). Does anyone else have this problem? How can I get it to take 30 gallons to increase the drive range?

When my low fuel light comes on, I still have 6 gallons. The only way to sqeeze 30 gallons into one of these tanks is to run it completely dry first, but you're not really accomplishing anything by doing that.

When I get a new vehicle I like to put a 2 gallan can of gas in the trunk then drive till it stops so I get an idea of where empty is on the gas guage. (obviously not on the highway or anywhere I can't just pull over)

I had an 88 celebrity once that would quit when the guage read 1/8 to go. Then there was the 76 triumph spitfire with a 7 gallon tank and the guage always read 1/2. Thank goodness that car was easy to push.

The gauge is just an aproximation. If it really bothers you that much, take the needle off and reposition it. But, be careful because you can make it off by even more by adjusting the needle. As for putting 30 gallons in, don't bother. You generally shouldn't run it that low anyway.

The in-tank fuel pump relies upon surrounding gasoline to act as a heat sink, drawing excessive heat off the pump while it's in operation. Regularly running the tank down to nothing means that the pump is running too warm on those occasions, shortening it's life. $$$$

Believe it or not, I can get 34 gallons of fuel if I put the fuel in very slowly.
