I am getting opposite opinions on which direction the delay valve is supposed to face. Harold, are you sure that the "dist" side goes toward the vacuum supply/tee fitting?

Was going to throw away. If anyone going to SEDOC wants, let me know and I'll bring with. My CPR is totally different, but appears from vacuum diagram in Tech Manual that "carb" nipple points towards Tee and "dist" nipple goes to CPR. Ford uses these things in horrifically complicated spark advance setup. When they switched to 4350 carburetor, moved spark advance to a full time vacuum port. Then had to route through delay valves and ported vacuum switches just to make engine run. Stupid. Bill Robertson #5939
