water in fuel sensor?

[bubbada]

I was wondering if anyone Modded a Water In Fuel Sensor for Petrol (not diesel) into Fuel Tank Or Lines, or do they even exist?
basically a for a warning if any water has been mixed in the fuel (preferably tank).
so how about it how do u know if there's water in your fuel any modding ideas?

500ml methylated spirits into a full track every 6 months is a cool mod

All the kids and pokemon players agree

Why wouldn't a tank of E10 (with ethanol) do the same thing?
