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)?

 

Page F99 of the USDM FSM shows a single spring clamp. Not sure what you mean by "Barb".

 

Something weird about this set up as demonstrated in the USDM FSM, bu tyou get the idea about the clamps.



The above is the set up for testing. Below is the set-up diagram.

 

i meant the barb on the fuel pulsation dampener. I circled it in blue in the attached image. Should the fuel injection clamp go on the barb or the stem where the arrow is pointing?

 

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 😅

 

the fuel recall added a second clamp, which basically solves the OP's problem. hose goes on, and then both clamps and there isn't any room for anything else

 

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.

 

thank you. I did it right then, I’ll throw a second clamp on and be done with it then

 

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.

The barb is the seal & the clamp holds the hose in place on the steel pipe. The clamp should be after the barb, not on top.

Worm drive clamps belong in the trash. If you must replace the OEM spring tension clamps, use bolt & nut style clamps.
