I recently purchased a '99 Xtra Cab, 2.4 liter, SR5. I've been operating under the assumption that the low fuel light doesn't work because it hasn't come on in the 8 months I've owned it. Recently though, I'm wondering if I'm just not letting the tank get low enough. I usually fill it up when the needle hits "E" and the tank will usually take between 11 and 12 gallons. The truck didn't come with a manual, but everything I've read online states I should have another 3 or so gallons for a total of 15. Does this sound correct? If so, just how low does the needle need to go before the light comes on?
Thanks in advance,
