Running a Liberty Fuel gauge sender in a MY cluster? Anyone done it? As the gauge in claudia has been playing up and i hooked up the liberty fuel sender and it didnt work. Sorry background, i will soon be running a custom tank with in tank fuel pump and hopefully liberty, etc sender in it if i can get it to work. (EA81T, see Claudia's details below). I am not interested in swapping instrument clusters too.

you confuse with words chosen, but you mean you wanna try a gauge display from a Lib jammed in the MY dash, gauge inside, sender in tank ?

If you have a friendly auto electrician rthey likely have resistanc readings for both in a huge book or CD. Or, get a diode wheel from DickSmith and dial up a resistance and apply to the gauge, one clip to ground the other clip to sender wire that goes to gauge - you get an idea of the range of the gauge from the readings on the wheel. A multi meter and sender unit out of tank should give ida of senders working range. Some work from something like EMPTY 10 Ohms to 110 Ohms FULL or vise versa

I believe if you use the liberty sender in the tank and have it wired how it was wired in the liberty (from tank to cluster) it has a high probability of working.

The best way to find out would be to get a copy of the liberty FSM, find the wiring for the sender. then set up a test bench with all of the components wired properly and actuate the fuel sender, and watch to see if the gauge moves as it would in the fuel tank.

This is the same way I test motherboards and cpus before I build complete systems

I have done it the other way around. Using a brumby sender and a forester instrument cluster and it works ok but not perfectly. 3/4 = 1/2, 1/2 = 1/4 and 1/4 means go to the servo soon.
