Does anyone have the part number for the check valve in the fuel distributor for a 1980 CIS setup?

Me and Doodle were chatting yesterday and I realized when I went through my fuel system, I replaced the check valve at the pump, but not the one that screws into the fuel distributor. For some reason, I can't find the part number for the fuel distributor check valve in PET.

Any ideas?

Do you mean the system pressure regulating valve?
I thought you should only change the small rubber ring on the valve, not the whole valve?

Here is the page/part from EBS Racing. I recently ordered this kit from them and it solved my hot start problem.
My o-ring had a chunk out of it. Probably in some instances can get away with just replacing the o-ring.
Not particularly cheap for the kit.
This comes up when I searched for my 1981 931, might want to double-check for the 1980 and if yours is an na.

Double-check the application for your year and model - the one below is for a 1981 931.

Talking about the little fella that's built into the fuel pressure regulator?..
I usually see it referred to as "push up valve".
It serves as a check valve to block flow and prevent pressure loss from the WUR back to the tank on shutdown.
Ya, I would think all you need is an o-ring kit at $1-$2.
