Love it when a plan comes together! I replaced a leaky high pressure hose over the summer. Was leaking near the pump, but after degreasing, I could see it was the actual hose leaking.

Also, the clamps and hose ends where the hoses attach to the bottom of the reservoir (both are low pressure) sometimes crumble and leak. Definitely check there
