Minimum Fuel
Tardog has it right! I have experienced running out of fuel with 1/8-1/4 showing on the gauge.
I had just crested a hill on the farm, was facing downhill on a pretty steep grade when I spotted a doe and her fawn being chased by several coyotes. I stopped to watch, cussing that I didn't have my varmint rifle with me. I left the truck running. This went on for several minutes, the coyotes got kicked several times, and gave up.
I idled down the hill, and the engine quit, and I could not get it restarted. I had 16-18 psi fuel pressure when I looked. I hadn't looked at the FP gauge while I was on the hill.
I ended up trailering the truck into the dealer for them to get it started. They have a electronic box to attach to the VP to make it pump if it is able to.
I have 15K miles on the truck since, and no problems have shown up.
So when I get below 1/4 tank, I treat it as empty, it usually takes about 25-26 gallons to fill. I don't mind carrying around 8 gallons of extra, it is much better than walking! Or killing the VP.
