Which fuel sender?

[d3mac123]

Hi, the builder of my Velocity did not install fuel senders in the main tanks (he opted to install one in the 6gl sump tank only). I'm considering the idea of installing senders in the two main tanks but, not being a builder, I have not idea/knowledge of which senders to buy. Thoughts?

Any help is appreciated.
Thanks!

Hey there. Who better to answer your question than someone who built a Velocity, added fuel senders himself, and made it work with his Dynon HDX? Oh, that's me

Centroid products FP1212V3. The units are labeled as 12V, but per their tech support the acceptable range is 11-28VDC. They work by providing a voltage on the SEND wire that varies based on fuel level. Per Centroid the empty tank voltage is 0, and the full is 5V. The unit has 4 wires (2 ground[black], power in[red], send power out[yellow]). Per centroid about the 2 black wires: ground both, as the 2nd black is just used to help differentiate from older models.
