Yeah I've been looking at the hoses for last couple of days, just thinking to myself man I oughta just rip this crap out and put new in. Think I'm gonna wait til it warms up a little more before I tackle that and in the meantime I'll just plug this check valve and hope for no more grinding. Can I leave the connector on the hose that goes to the solenoid open or do I need to cap it off too? I promise last question for today LOL thanks.
