2 questions

My first question: Does the regular magom hydraulic elbow keep the hose attached to it, or do I need something to keep the pressure from kicking the hose off? Because I've seen a lot of people's hydraulics with just the hose attached directly to the elbow with nothing on it. Can I do that without the hose flying off?

My second question: Would I be able to increase the pressure on my centrifugal pump by putting a higher rpm/kv motor on it?

Thanks
