That's probably not a good ground; Joe's suggestion of drilling a hole and
using a self-tapping screw is probably best. it needs to be connected
tightly to clean, bright metal. A squirt of spraypaint on the screw, wire
and metal when you're done will keep water and corrosion out later.

By this I assume you mean connect the (yellow?) wire back onto the sender in
the tank, not some separate power wire... you'll likely start a quick and
serious fire i you wired 12V onto the sender. The sender is connected
(through the harness) to one of the terminals on the gauge, only. Just
double-checking.
