The photos show the left side of the pressure regulator of the fuel distributor. Note the O-ring on the head of the red "pin" or nail that seals off the warm-up control (WUC) regulator on shut down. Opened when the silver piston of the pressure relief shifts left.

Photos taken 2 years ago when I didn't know its function. I wonder if the rebuild kits for this include 3 O-rings for the pressure relief valve.

If a new O-ring doesn't seal off the WUC, another option could be to trim off the pointed red end on the right side where it hits the piston. Would allow the O-ring on the left end to have more squeeze to it.
