I was hoping to hit 500 miles

The pump sits in a bucket on the floor of the tank. It self-feeds so the bucket is always full even when the tank is very low. The pump is always surrounded by fuel, even down to the last half gallon or so

 

I did hit 460 once. Mine was a 10-14 days normal daily driving with some weekend trip. Iirc, my average tank was 24 mpg. Truck had oem Firestone tires. 420 was pretty normal

 

Thanks!

Mine is a DCSB TRD Sport with the 3.5 V6, 4WD, and the 6MT. It has hit 400 miles well before DTE=0 a dozen or so times now, but I typically drive faster than this trip; I think 430(ish) was my previous best.
