Scirocco Register

Hi all!
I'm fitting a custom dashboard to my 86 gt and need to know the resistance values from the fuel level sender to the gauge on the dashboard

I found the values for a rabbit but I'm unsure if these will be the same
It's for a 55 litre carb model if that affects it at all

Thanks!

My spare sender for carb engines measures 300 ohms on empty and around 30 ohms on full
