I have mine chained with a stainless steel which goes down into the tank.
Whenever I gas up I always hook the ground cable to the stainless cable
which is in my tank. I am assuming that will provide a good ground. How do
you get a ground?

There was big discussion years ago in the EZ community concerning caps on
chains. One side said chain them on to save them (from loss and props
strike). Others said let the the cap depart to avoid the cap violently
beating the fuel tank in flight in the airstream. Bottom line was that the
caps a lot of the EZ's used back then were (per plans) cheapos and not
aviation locking grade spec'd out on Velos. I'm very comfortable with my
Velo caps unchained and would not consider chaining them.
