Default Injector pulse dampener?

I bought an aftermarket fuel rail on eBay and received it.



Notice the middle port.

I asked the seller about this extra port and he said:

Yes that is indeed the correct fuel rail that you received. The middle port isn't for an injector but for the fuel pulse dampener according to Auto Gear's tech line. It's an oem fuel component that you plug right into the fuel rail.

So the question is where the heck do I get one of these fuel pulse dampeners? Is it a part I can get from Dodge and it will just "plug right in"?

Stock fuel rail:

Um...no dampner on the Boomba rail - None on the OBX, and None on the Perrin I have as a spare.

I can only guess that this fits a normal 2.4L and some OEM part (Chrysler maybe) fits in that hole.

But thats a new one on me...Strange.

But, a very good idea, nonetheless!

So could I just cut it off there and weld a plug over it? Or should I try to get my money back since there is no injector dampener I can buy to put there.

Edit: Got another message back from him.
I asked where I could find one of these injector pulse dampeners.

Yes your correct, but you have to remove that oem fuel pulse dampener and put it into your Auto Gear fuel rail. It comes out just like one of the injectors with a clip. The second generation of SRT-4 fuel rails has that port for the fuel pulse dampener because your engine will vibrate without the fuel pulse dampener in the fuel rail.

Ughhhh what.

Well, it takes a little tenacity with one or two small flatblade screwdrivers, but you can get the stock one off your original fuel rail, and put it on this one. I would do that over welding that thing shut, no question about it.

Problem is I don't have a stock fuel rail. Just a S3 rail with the rising rate regulator.
So it does indeed come off.. Question is..Will it seal well if I were to put it on my AutoGear. It should.
I wonder if the injector pulse dampeners are the same size on all the neons. Could go to the junkyard.
Edit:
No, reg 2nd gens don't have them.

Talked to a guy in Toronto Canada who is selling an 03 rail. He was kind enough to tell me the numbers on the injector pulse dampener:

04591758AA

Also has 0063 BT 400KPA stamped on it too.

I googled the numbers and found nothing. PM'd a user that is a parts guy for dodge.
Will be pretty sweet since I will be the only SRT-4 with this rail it looks like. (If it all works well that is)
Also got this message from the seller before I bought it:
Quote:
The reason why this is a liquidation sale is because Auto Gear moved facilities so we picked up a good amount of their inventory to cut their moving costs. FYI this is the same machinist who cut AEM's first generation of cam gears/fuel rails years ago if you still doubt the item for sale.
