Feel free to call me an idiot if this is a stupid idea, but do I really need to replace them if I'm re-using the same hose? I'd rather not cut the hose shorter if possible, as it's about the perfect length right now.
I'll give it a go and if it's not sealing I'll take it into a bike shop. TBH if it gets to the point where it needs a new olive and barb, that's the point at which I'm happy to pay a shop to do it, rather than attempting to do it myself!
Thank you so much! So doing a bit more research, it looks I'm gonna need some new tools if I replace the barb and olive (https://epicbleedsolutions.com/collections/shimano/products/shimano-hose-shortening-kit).
