I popped a fuse that no one has in stock and I may have to tow my Subaru legacy awd home. Is it safe??? Need to go about 4 miles

go slow, you should be ok.

 

but don't you have all the fuses from the parts car?

Parts car? You must be thinking of someone else. I got her home.

too late but for future reference, if everything is normal - just swap in another fuse and drive it. if it's a regular fuse or fusible link, just swap it in, don't do anything crazy and it'll be fine.

It was one of those 45 amp fuses under the hood. I have no clue why no parts stores stock them.
