fuel gauge??

[StephenB]

I wanted to add a second fuel gauge to my RX8. Anyone have any suggestions on where to get one and how to mount it inside the stock tank. It DOES have an access panel. (Fuel tank is designed like a saddle) For the guage I would like to have something with green. yellow and red lights so that I don't have to "read" it and I can just see it...

You're buying that Canyon fuel gauge thing, right? The one that converts the signal from the stock sender to voltage? Then you need nothing else in your tank.

Install that, and then find some kind of "gauge" that has all the pretty colors and uses voltage for an input, something like an AFR meter. Using resistors as appropriate, calibrate that gauge to show you all the pretty colors as the fuel level goes down.

I guess what I really am looking for would be a sender to go with a guage for the tank. basically I want two guages. one for the left and one for the right.

Does not the tank system have an equalizing tube? If so, dual senders is redundant (and why Mazda did not do it).

Why not one of these for a sender? You can trim it to length. As long as the tank has a flat spot on the top you can get that ring to mount to and seal, it should work. Not sure how to have it make the change from red to green based on fuel level. I would be curious to hear how to do that myself, not that I have a need for it, but I have no idea how to do it.

Autometer now has a number of gauge/sender combos that are programmable. Here's an example:

I use a low fuel light. You need a float/bracket ass, and add a contact to the sender board or make a new board. I make the light switch.
