Is there available such an item as an in-line BS1362 (or other type fuse) fuse holder/carrier ...

There are plenty of DIN rail mounting fuse holders, if that's the sort of thing you were thinking of?

A Weidmuller ASK 1/15 for TS15 rail is probably one of the smallest, but is only rated to 6.3A. Probably need to go to TS35 size if you need higher rating.

edit: if you mean automotive blade fuses, they are normally rated 58V or less https://www.littelfuse.com/~/media/automotive/datasheets/fuses/automotive-fuses/littelfuse_maxi_58v_blade_fuses.pdf
