Reply to "Gas gauge tank float problem"

Is there an epoxy that will stand up to gas?

JB Weld makes a fuel tank repair epoxy that's impervious to gasoline: https://www.jbweld.com/product/j-b-weld-tankweld

Just FYI, I've had the aforementioned VDO 73-10 ohm stock VW replacement sender in my tank since 2018 when I changed out my gauges and had absolutely no leakage issues. I coated both sides of the rubber gasket with Aviation Permatex. O-rings aren't required with the VDO sender. 

A word of advice: wear a grounding wrist strap of the type used for electronics, and maintain a common ground to the tank and wrist strap when changing the sender. You wouldn't want a static discharge to ruin your day.
