Low Fuel Warning/Resetting the computer to show 88 gallons
A friend of mine (who has a Chevy) and I, with my '09 F350 6.4, have a question about the Low Fuel Warning as we are both getting 50 gallon aux tanks from Transfer Flow with the TRAX II system. I've been under the impression this was activated by the level of fuel, as measured by the trucks fuel gauge, from driving a '05 F250. Another person says (not my friend) that this is activated by the computer, based on the number of miles driven and the MPG, another function of the Miles to Empty calculation. Any info on which is correct.
And is it possible to get the computer reset from 38 gallons to 88 gallons? I doubt it, but it never hurts to ask.
Thanks

The transfer flow tank transfers fuel into the main tank automatically and it has a displa y readout which tells you how much fuel is in each tank. It does not pump fuel from the aux tank to the motor it just fills the main tank. I have had a 98 gal transfer flow tank for about 5 yrs now. If I can make a suggestion I would say to install a fuel filter in the hose coming from the tranfer tank before it goes into the filler neck of your main tank because it will pump trash into your main tank as it does not have any filters on it. The system works o.k., but I do not find the guage on the transfer tank to be very accurate. The way it works is they cut the wire coming from the main tank sending unit and run it through the control then tie back into it going to the truck guage.

The new Transfer Flow tanks have a fuel filter and the computer plugs into the existing wire harness and transfers 3 to 5 gallons at a time with the TRAX II system. So the fuel gage on the dash reads full until the aux tank is empty. Which means the Miles to Empty and MPG info is going to be WAY off, so if that information is used to activate the Low Fuel warning, instead of the reading direct from the tanks fuel gage, it will be a Royal PITA.

The TRAX II displays the main tank, aux and total fuel levels and when the pump is on or any TRAX II error code(s) if any. There is also a different system called EXPRESS-UFS without the computer display that transfers fuel when the tank gets below 3/8 - 5/8 until the level reaches the 5/8 -7/8 level. When the level drops below 3/8 on the gauge the aux tank is empty. There is a Momentary Switch available to manually transfer fuel. So if you held that down till the guage shows full I guess you'd get a ballpark MPG, if you didn't overfill the main tank driving down the road. I prefer to know each tank level so I'm getting the TRAX II.

I just had the Transfer Flow, Inc. 50 gallon aux tank/toolbox with the TRAX II system installed in my '09 F350 6.4 dually. Then I made a 500+ mile trip with the 5er in tow without a fuel stop. Some things I learned at the Transfer Flow, Inc. facility in Chico, CA.
1. The low fuel warning occurs when the resistive value of the OEM fuel gauge reaches a value equivalent to appx 1/8 tank, at which time the OEM computer activates the "Low Fuel" warning.
2. After the Transfer Flow tank is installed there will not be any "Check engine" warning or codes set because the OEM computer thinks you've gone way to far without refueling. The TRAX II system transfers 3 gallons or so, and then shuts off. So as far as the OEM computer is concerned, you just "Topped Off". I verified this on my trip home from Chico.
3. The MPG and Miles Remaining to Empty are worthless now. You're back to figuring your own MPG.
4. The OEM fuel gauge always reads the current amount of fuel in the main tank, only. So when the aux tank runs out, what you see on the OEM gauge is what you got, period. And refer to #1 above about the "Low Fuel" warning, and look for fuel if you get that low. The TRAX II always shows the Main, Aux, and Total Fuel levels in gallons.
5. What a feeling just going and not worrying about finding a fuel stop when you're towing a large 5er. It's much easier to plan trips now.

I have the Transfer Flow 50 gallon tank on my 2008 F-250 6.4L and it works great. The trax II shows the main, Aux, and total fuel levels in gallons. And the OEM fuel gauge shows the total of both tanks, when it reads full I have 80 gallons half full I have 40 gallons. The MPG works just as good as before.

I'm glad I sparked some responses, when I was researching and looking for information about a aux fuel system, including talking to my dealer, asking questions here and on other Ford boards, I heard every thing from "Check Engine", throwing codes... I didn't know what to believe. So I decided to do it, buy the darn thing, and get the true story out.
I was wondering about the MPG readout, but I'm on my first fill up and thought I check that against my old fashioned way before I said anything.
And, for what it's worth, Transfer Flow makes a darn nice product.
