Does the fuel hose clamp go on stem or barb of FPD?
attached is a photo of the FPD and where I currently have my fuel injection hose clamped (on the stem where the arrow points). Is that ok or does it need to be at the barb? Is it ok to have two clamps (one at barb and stem)?

pictures here really don’t tell me if the clamp should be on the barb or stem of the FPD, that’s why I’m confused 😅

I always place clamps on the flat area. The barb is to prevent the hose from sliding off the tube. You do have to assure the clamp is tight enough to seal.

I just did this not too long ago and mine had the fuel recall done to it so there were two clamps on that hose. One right after the barb and a secondary clamp right behind the first clamp so two clamps on that hose. Below is a picture of the hose coming from the FPD to the fuel hard line, but you can see the two clamps on the fuel hard line.

I am gonna check if all my clamp spots are double clamped!
And with the correct sized clamps.
I think there are even more robust fuel line clamps available.
I note that contrary to the diagram, my Version 5 car had much more substantial fasteners on the line between the two rails.

For what it's worth you never put a hose clamp on the barb, always on the body of the pipe.
Putting it on the barb defeats the purpose of the barb. You are clamping before the bump, if there's any pressure trying to pull the hose off it can't come off since the clamp pressure can't get past the hump. If you put it on the barb you may as well not have the barb, it will decrease the strength of that connection significantly.
Also OEM hose clamps properly installed will never give you a problem. Avoid aftermarket fuel line clamps if possible, especially cheap worm drive clamps that tear up the hose.
