Well, that certainly looks like a 'hose'!
In the absence of a Bedford dealer (!) I would approach any industrial hose supplier (there are many such companies supplying hydraulic hoses for construction machines - JCBs and the like):-

Remove your part and take it in and they will have a suitable replacement made up while you wait - that's what they do for a living!
Are you certain that your hose is faulty? It looks 'good'.
