Yes the fuses are still available. I suffered a 'meltdown' of a plastic fuel pump fuse not too long ago'
I ordered a set of original spec jobs from Rufe on here :

Yes the contacts should clean up okay. A bit fiddly maybe. I used a light grade of emery cloth & then a spray of electrical contact cleaner to remove any left over debris.
If you still need to joggle to get contact, remove that fuse. Then gently try to close the contacts a little to make the fuse fit tighter.
Good luck
