Hi guys! Can anyone please recommend fuel sensors for the wing tanks? I had magnetic switch float type sensors that turned on a panel light when the tank was nearly empty that where purchased from Compac Engineering, but the last one failed in only 90 days, they will not replace it, and their service sucks ( don't buy from them!!).

Thanks.....Dean

Dean, you will have to keep us posted on whatever solution you come up with. I never was able to figure out a good fuel level gauge for my wing tanks, so I just use a timer based on the rate of my fuel pump.

Turns out the 6905-400 has pipe threads. The best to use is the M7790. It is available from Granger.

I have a WESTACH FUEL SENDER AP-Q24B3-D120-5V in my header tank and find it ridiculously accurate. Don't know if a version of it would be the right choice for a wing tank, I ain't got no wing tanks.
