Fuel sender / Internal battery

[echo_sierra]

Hello,

First off all i would like to install a fuel sender and would like to know if this one would be good:

It will be installed like that:

Also, my internal battery goes from fully loaded to low in just one week staying in the hangar at +/-20°C... Any idea?

Regards

That sender should work just fine. Its resistance range is different than a lot of the fuel level senders we've seen. But since we require a calibration on fuel level, so you should be just fine.

As for the battery, that does seem rather fast. What voltage are you seeing on the battery when it's fully loaded? Is the unit turned on and running off the internal battery at any point during the week? Or is it just turned off? Also, for reference, when did you receive your unit?
