When they rebuild the HP hose they basically reuse the metal ends and put a new hose of the proper rating beteween them. In the states some auto part stores do it, someplaces you need to find a place that repairs hyraulic driven heavy equipment like front end loaders.

Unless you know that the pump is bad, just do the tank O-ring first, that has solved many people problems.

For the low pressure hose, you can reuse the clamps if they're in good shape. If any doubt, get new. I prefer the Subaru clamps that are heavy wire looped around with a screw, some like the normal worm clamp (flat strap with screw threads cut into it). For the hose, not sure if it would be called 3/8" down there, take a piece of the old to any autoparts store and tell them you need a couple feet of it, if they ask what it's for, tell them for an Auto Trans fluid cooler.
