After a few weeks, the fuel lid would not open. The metal tab lost
its "spring". I immediately searched miata.net where I
got the idea for this fix...
Parts:
spring
screw
nut
washer (diameter must be larger than the spring)
rubber washer
Here are the parts. Drill a hole in the metal tab, as shown above.
Pinch one loop of the spring between the metal tab and the washer.
Use the screw and nut to hold them together.
I added the rubber washer to keep the spring from scratching the plastic
gas cap. I used silicone glue to attach the rubber washer to the spring.
As you close the lid, the rubber washer should rest flat against the
gas cap. Use needle-nose pliers to bend the spring if necessary.
