Jubilee hydraulic update

[Al in Il.]

Yesterday I posted a question about a Jubilee back pressure gasket - I made one that fits perfect with no leak. Now it looks like another valve
is leaking. According to my FO-19 IT manual, the check or safety valve is faulty. I intend to order a safety valve, part number NAA984F (8N638
for the 8N, interchangeable I believe). I cannot find a Jubilee check valve for sale, just the safety valve. Anyone have a part number for the
check valve and where to get one? I'd like to replace both at the same time and be done with it.Thank you, Alan.
