Volvo use a cheap low pressure hose not much better than a garden hose, that’s the problem. They could use a flexible half inch single wire reinforced hydraulic hose for pennies more cost that would never come near bursting at the modest pressure peak of the power pulse system. Unfortunately the crimped-on terminals are unique to Volvo as far as I can see, so the only way to patch a hydraulic hose to them would require some careful sawing and welding or brazing.
