Car adapter fuse

[Hippytipper]

Quick question. Picked up a Game Gear I plan on refurbishing and I got this car adapter with it. But it doesn't have the fuse, cap or metal pin.

I plan on fixing this just for the hell of it. What kind of fuse do you think this would take?

Radioshack could tell you the size bit the rating would 250V @ 1 or 2 amps.
