I don't have the Quick Disconnect version.
Hose works fine, hose with spindle (also tried a second one) in place works fine, no visible debris in end of PP2. I called tech support and he didn't have any better answers, so I'm sending it in.
They have a 2 year warranty, but it's been 3 years since I replaced my PP with it and then replaced the first unit 6 months later, etc. I guess it's possible that when the hose failed some salt water got injected into the gauge, although that seems remote. So I'll probably be out $150 for a rebuild, unless it's something simple.
I'll post back once it's repaired.
