Yes I am! But do you happen to know the Ohms??

I asked the same thing b4 and this is what Russ-D said:
"usually fuel cells come with GM senders, which work opposite of Mazda. A GM sender is 0-90 ohms, which means it is 0 when empty and 90 when full. A Mazda is 100-0, which means 100 when empty and 0 when full. (most senders wont read actual "zero", which elctrically would be an open circuit, but will read very close to zero).

So if you hooked up the one in the cell (and it is indeed a GM) it would read backwards, meaning empty when full and full when empty. An older ford sender was very close to the Mazda, it read empty around 80 and full around 10 if I recall correctly, which would read the correct direction on the stock mazda guage."

Well then I guess I can use the GM sender I have an autometer gas gauge I guess I will just replace it with that so it will read correctly. Thanks I was seeing if I needed to replace the sender or if I attached the guage to it, it would read on my autometer gauge correct from what you say it wont read correct so I need to get a new sender for that guage.

I am using an autometer gauge with my RCI fuel cell (0-90 ohm)
