Default Fuel level with Holley dash
Hello,

Does anyone know which parts/wires I need to install a fuel level gauge using my Holley dash? I have a ricks tank with the tube level.

Thanks

Not sure which dash you have, but the standard 7" uses a tan wire for the fuel sender. It looks like the dash comes with everything needed to hook up to the Holley EFI system and display what's happening there. But for additional inputs like fuel level you may need to get a separate I/O harness from Holley to have the wiring needed, not sure if it comes with the dash itself.

And one of these then terminate what wires you need into it. Don't forget pins if needed.
