What is the correct part number for an HZJ73 vane pump's flow control valve

[itamar]

Hi,
I'm doing a complete rebuild of my 1998 HZJ73 vane pump.
I've ordered the gasket kit, bearing, shaft & would also like to replace the flow control valve.
I found 3 part numbers and not sure which is the correct one:
44330-36140 - "Two Groove"
44330-36150 - "One Groove"
44330-36160 - "No Groove"

I'm attaching a photo of the one I took off my pump & would appreciate it if someone here can help me find the correct one.

Thank you,
Ari.

Hey there. Did you find a result? Just rebuilt my pump and only thing i did not do was dismantle the valve. Its much better, quiet and working as it should, but isnt any easier. Still kinda not easy. My valve had no shims in it. And im wondering if thats the issue. It had been rebuilt another time before i got it. Maybe theres too much tension on the spring. hmm. Anyway good luck!
