Melting fuse?

Hello -
My car has melted the plastic part of fuel pump fuse a few times this summer - so I thought I'd post a question about it. See the photos below for more detail. It's always in the same manner - the plastic at the bottom of the fuse gets hot enough to melt, thus shortening the fuse so that it doesn't fit snugly in it's socket, thus current won't run through it, thus my fuel pump won't run. Please note that it's the plastic melting - none of the fuses have ever blown. I've only had problems at start up, it's never quit while running.

It's only happened w/this particular fuse. I've looked over the socket and it's almost as if the hole at the bottom has become enlarged to the point where the fuse sits too deeply, almost allowing the plastic of a new fuse to touch - or get close to the bottom of the socket.

Is this an electrical catastrophe waiting to catch my car on fire? Hopefully that's not a stupid question w/an obvious answer. I've assumed that since none of the fuses have blown, that there's no voltage spike happening.

Thanks,
Tom
