When my truck was new, if the low fuel light came on, I could pump in 22.5 gallons. Now days I can get in almost 25. I know, tank shouldn't hold that much fuel. Did that tank expand or do the filling stations come up with another scam? Recalibrate their pumps when the state isn't looking?

The fuel senders in the tank are not that extremely accurate. I have never seen my low fuel light come on, but I did fill up with 25 gallons one time (I have a 26 gallon tank). Another thing that can make a difference on how much you fill up is how fast you pump. The fuel will foam and sometimes you could get as much as 2 extra gallons in the tank if you try. Personally, I don't ever run the tank that low if I can help it. I have only run it low 1 time. I would not make a habit of running the tank low to the point the light comes on since all the crud is in the bottom of the tank.

The manual for my truck informs me that fuel tank capacity is 24 US gallons. I try to not run it real low either for the same reason you do, let the sediments stay right where they are, on the bottom. A 24 gallon tank, engine is still running, low fuel light not on yet and I put 25 gallons in it?
I can see the foam or an inaccurate gauge but I'm still trying to figure out how to put 25 gallons into a 24 gallon tank.

The shortbed trucks have a 26 gallon tank. Crawl under your truck and the tank should have that on it. Your manual must have a misprint in it. According to the manual I have, chasis cabs have 23 gallon tanks, but shortbeds have 26 gallon tanks.

Yeah....the manual I have said 24 gallons. But I crawled underneath my truck and it was a 26 gallon. And I'm glad I learned about the whole foaming thing....because you can get alot more in there if you use a flashlight and check out the situation.
