Happy Holidays!
Before going outside the build manual instructions for the fuel
tank, it might be worthwhile to recheck with the factory. No
offense to Roger, but the company is now owned by an actual
aviation engineer.
The presence of a conductive patch in the tank is meaningless, the
only thing that matters is the possibility to close a path to ground
---From a voltage source(like a static, or in engineering-speak, tribolelectric
charge) through a fuel-air cloud.
Unless the tank is electrically connected to the engine block or other
ground there is no ignition circuit.
BTW, the best fuel hose available is Aeroquip 666 with a carbon stripe
on the teflon inner liner to move fuel-flow induced charge to a controlled
ground site (not through gasoline-air vapor)
Best of Luck,
