F 450 mileage improvements
2000 F 450 with 7.3 diesel. automatic quad cab with 4-88 gear ratio.
What can I do to improve mileage. I am always hooked to a trailer. Not sure if a chip or cold air induction will get the most bang for the bucks. The gear ratio is great for heavy hauling but I would like to get the mileage better. 63 mph at 2500 rpm on the tach.

Thanks for the reply. I see that you have done the Hutch mod. I have foam in the main tank after I have driven it for an hour or so. If I fill up at the first of the trip, it will take fuel with no problem. I have an added aux tank with a traxxus fuel transfer system. The bed is a Western Hauler aluminum so the aux tank is a rectangular box. The 2 hold about 75 gallons total. Filling up at a truck stop with the high flow nozzle is a waste of time. I typically have to gently squeeze the trigger on a conventional pump. It is a trickle and takes a long time. Getting ready to pull our RV to Co in July. Would like to not spend my vacation hanging around a diesel pump. Any ideas are appreciated.

there are a lot of things that should help gain mileage. intake tuner exhaust are a few. full synthetic fluids could possibly help. i have also heard that the ebp sensor has a lot to do with mileage. so try cleaning that and the tube. also check your up pipes if they are leaking you are loosing boost and there for loosing power. so that means less fuel mileage.

I did mine a couple years ago. Only have to trickle the last couple of gallons in. I also would get rid of the in tank screens while you are in there and install an inline filter between the tank and the fuel pump.

Very heavy truck with 4.88 gears will never get the same mileage as our pickups do.

I also have the Transfer Flow auxiliary tank so I usually fill about 15 gallons in the rear tank and then fill about 15 gallons in the aux tank and then move back to the rear tank etc. This usually gives enough time for the foam to dissipate and makes the fill up procedure a little quicker as well.
Drop the tank and do the Hutch and Harpoon Mod. It will make a world of difference when filling up.
