    Diagnosing dual tank balance module

    I know what you mean, I just decided to change mine because I thought the way the stock system worked was kind of retarded. I hated having to top off both tanks every fill up and when the balance module crapped out I end up being stranded somewhere not realizing that I was out of fuel due to the...

    Diagnosing dual tank balance module

    You can just hook the sending unit directly to the dash gauge, I did that and it works just fine, although the dealership said it wouldn't. I used a two position toggle to choose which tank to read from and put my transfer module on a toggle as well, way cheaper than a new balance module, and it...

    Diagnosing dual tank balance module

    How much does the ohm reading change? Most likely when the key is on the module is activated and both tanks are connected as one circuit, when it's off they are separated again. I have my rear tank on a toggle now and it works great that way, I have it hooked through the factory wiring though...

    Diagnosing dual tank balance module

    No I was going to but decided to try and rewire the system myself. I used the old balance module as a connector for my new wiring in case my mods didn't work and I had to go back to the old way. Everything works fine now. Only one small problem of the fuel gauge needle moving around a bit while...

    Diagnosing dual tank balance module

    Not totally, the transfer module was fried as well. The hard part was that the gauge was stuck on empty and when I tested the module for some reason it was sending that signal to the gauge. Usually in the past with any other vehicle I have had the problem is too much resistance, not too little...

    Diagnosing dual tank balance module

    Well I just went through hell trying to get my rear sender out, and of course it is fine. So I put it back in and of course the gauge didn't work. Turned out to be a bad connection in the plug, works great now, and I may have even stopped the leak as well. Somewhere in this thread I think...

    Diagnosing dual tank balance module

    Not just the WEB, but even the dealers don't have a clue how this works. I thought my fuel gauge was no good, so I bought another cluster from a wrecker, but it turned out to be the transfer module. What got me thinking of rewiring the way I did was that the new cluster came from a single tank...

    Diagnosing dual tank balance module

    Well, I just decided to get creative with my old transfer module. Managed to open it up and solder on a short length of trailer wire to the B,C,D,and F terminals, and ran that to my dash. A few minutes work and now I have both fuel tank senders wired through a 3 way switch and the transfer pump...

    Diagnosing dual tank balance module

    I'm glad I found this thread I just spent 9 hours stranded on the highway after the truck died, and after spending $1000 at one supposedly expert diesel shop for an FSD module and almost another $4000 at a dealer for an injection pump, I luckily decided to just tow the truck home and fiddle...
