IF you get 13-15 consider it good... YMMV depending on driving conditions

thats better than I expected considering the injectors are original as is the injector pump. I found out through work that the manual lift pump is still available through Ford for the 6.9 and 7.3 IDI trucks. It goes for at non employee price of $45 USD. The show a stock of 350 in Detroit and over 1,000 in the states. So a odd ball part still available when brake pads for vehicles with a GVW over 8500 lbs are not. Its kinda like ok the part that brakes occasionally we still make but common items that wear out we don't. I find it amusing that Ford does that.

It reminds me of a 60s and 70s ford small block or inline 6 fuel pump. Wonder if it is.

that makes sense. Seeing that the V8 mustang and Bronco shared a lot of parts. Got one more nagging issue. My PRND21 is way out of wack. In reverse it shows park reverse is neutral and neutral is drive drive is 2nd and 2nd is 1st. And the parking pawl does not engage fully unless I slam the shifter into park. Its a rod linkage and I want it to be correct.

chocks the wheels. remove the shift rod from the shift arm on side of trans. put trans in park.
key off lock position so you can move shifter, put shifter in park. go back under and adjust rod to fit shift arm.
put it back together and test drive.
if the shifter is now good, remove right side lower dash and the PRNDL is adjusted by the little plastic turn wheel on the shift indicator cable.
this one is for a C-6 trans but should also work with an E4OD:

Don`t get the illusion that the front tank is bigger because it is longer.
Front and rear are 19 gal ea. Most likely the same as my 86 F250.
I have the 6.9, t-19 4-spd and 3:55 Diff, and one wheel drive.
I can click along on an average of 20mpg. Some times 18 and go as
high as 22 on one tank.
This is running empty, = no load.
You have a 91 F250 7.3 IDI E4OD 4 x 4. What Diff? probably a 4:10?
You do have the Over Drive Trans. But the auto`s do for the most part
take a bit more fuel to operate compared to a manual trans.
For your year, and manual would be the ZF-5, which is OD.
if you had the 3:55 Diff. that also would help with mileage, and your
driving habits are a big factor also.
I fill my tanks to the brim of the Fill Tube every time. Write down the
OD reading on the recipt. Next fill do the same, subtract to get the
miles driven, divide the fuel it took to fill tank, and that is your MPG
for that tank.
You cannot get a correct answer saying I drive 350 miles between
tanks, is that good?
When I fill the front tank to the brim after the handle click off, I add a
good 3 gallons. So probably 22 gallons.?

That sucker was long.....no way it would have fit with a transfer case. Idk if it came out of a cab and chassis or what? Used the standard for sending unit iirc
Rear tank was your standard 20 gallon.
