I put a HPOP gauge on my truck today.

I have about 5000 miles on the shingle shots. Have haven't unhooked my 32' flatbed goosneck from this truck since I put in the injectors and the HPOP in.

I have a 91 gallon and 40 gallon fuel tank, I fill up at the same place most of the time (Pride in Palmer, Ma 2.999 the past 3 weeks) I check my mileage every fill up. Sometimes I only put on 100 miles then top it off the last tank I ran 1148 miles (took 105 gallons 10.9mpg)

I did a test run last week I filled up 145 miles from home and ran all high way no faster then 60mph mostly 55. I got 15.5 mpg, with an empty 7,500# flatbed trailer, with a F550, with 4.88, that is awesome. It was really hard to drive that slow for 3 plus hours. That was the best yet.

the wost was 9.3 mpg hauling a farm tractor (I ran 75 mph 2600 rpm) to New York and then a load of hay home (60-65 mph), this is very good for this kind of hauling.

I plan on putting a ZF6 and a F450 Dana 80 3.73 (unless i can find 3.73 for a spicer110) with a locker. Then I should be able to do better mpg.
