Dont attempt it yourself, But Yes it can be "chopped" to bypass the split section if you dont mind loosing a few feet, You should also ask them to pressure test the hose once repaired to ensure its strong enough for your machine.It could just be bad look or damaged but you need to ensure its strong enough for the job and not going to fail again.
A hose specialist should be easy enough to find online but if you post your location someone may know of one near to you.(shouldent cost much more than about 10-15 squid imo).
