I can’t answer that because I never run it that low. I start looking to fill up around a 1/4 tank. If I’m out west I’ll start looking at a 1/2 tank. My buddy learned the hard way not to push it. I told him before he left for a western trip “don’t run the tank past 1/4! There aren’t a lot of station around like in the Midwest”. Well he didn’t listen and he barely made it to the next station. He filled his Excursion’s 44 gallon tank with 43 gallons!!!!
Not to mention the fuel pump relies on the fuel to keep it cool.
