HW Cies Fuel Sender combo

[Montreal]

Question for HW builders. Is anyone installing Cies fuel senders on their HW and are you replacing all 3 (2 main and 1 header)? I contacted cies and they said they were not familiar with HW and have only worked with Sling TSi.

I specified CiES fuel senders for my factory built HW which has just completed test flying and is about to be loaded into a container for shipping. Early last month, I requested confirmation that they were installed in both wing tanks and the header tank and the reply was yes.

Thanks @reigate... Midwest Panel Builders has since informed me that they prefer to use the generic Sling header tank fuel sender as a "low" switch to send message to Garmin G3X crew alert system (Warning/Red) rather than showing a fuel quantity level in the header tank. The wing fuel tank senders are the same as the Sling TSi which you can pre-order on CiES website. Essentially 2 TSi wing senders and hardware from CiES.

Somewhat related. I've repeatedly encountered conversations in which people have been saying the TSI needs 4 senders (two inboard and two outboard) to cover the full range of fill states. With the reduced dihedral of the High Wing, I imagine just the inboard pair will suffice. There might still be a little lack of coverage at the full end of the range, but it should be substantially less gap than in the TSI, right?
