As the title which should I use to pass SVA (one's with inserts) and where best to get them from. Had a look in google and seems to be differing sizes of hose diameters. Thanks in advance.

-3 is normal for brakes.

Be interested in the answers to this as Ive used reusable jobbies on the front......

I've used the euroquip 600 ones from rally design. Not had SVA yet but someone here has with them and passed fine (might be Razman?), i've bought a spare fitting to show SVA man if he asks.
