What's the most gas you put into your truck at a fill up? I put "18.9G" in mine today...:rofl2::eek:wned:

I just found out we have a 21 gal tank.

Nice that I've never been as close to empty as I thought. I've had the needle bottomed out a few times for miles before getting to a gas station.

Nope, the pump is cooled and lubricated by the fuel that flows through it, not the fuel it is submerged in. You have to run the tank dry before it stops getting cooled.

p.s. for me it is right at 17.5 if I gas up as son as the gas light comes on.

Also, the fuel pump is in a plastic bucket in the fuel tank and the fuel return dumps into the bucket, so it is submerged as long as there's fuel in the tank. The bottom of the bucket has a one-way check valve, so fuel can go in, but not out.
