pressure drops to zero 1 hr after shutting the engine off. 

Pretty common for that to be caused by the FPR.

Zed Head, is the damper you’re referring to a direct fit replacement. I.m replacing the pump with OEM parts. Mine was frozen from rust in the tank. I would assume the damper is defective also. 

[Zed Head]

I referred to a bunch of them.  Not sure which you're talking about, but most will require some finessing to get in.  Even Nissan built a custom bent line to mount their stuff.  Study those fuel lines and you won't feel bad about adding a few more bends.  They're just well-done backyard mechanic bends.

Are the dampers prone to clogging? Mine has no Sign of leaking. 

[Zed Head]

I've not heard of them clogging.  I think it's just a diaphragm that flexes with pressure pulses.  The easy check is to remove it and see if it flows.  You'll probably want to replace the hoses anyway, they're old and on the high pressure side.

Update:

After much searching, I ordered this one from eEuroParts:



Somewhat disappointingly, it took them a week to ship it, and another four days in transit. But it fits perfectly.  As you can see from the part number stamped on it, it's the same BMW part Consigli found two years ago (280161024).  It just wasn't listed under the same part number.  Maybe that's why they hadn't sold out yet.









Just sharing in case it helps someone else.

the_tool_man Did this work for you? I found some available and would rather install this style than the one sold by Z Car Source

It physically fits.  But I haven't finished with the fuel system rebuild and other stuff to get the car started.  So I haven't driven the car with the damper installed as of now.  Honestly, of all the things that could go wrong with my work, this is the one I'm concerned about the least.  This is a simple part that is physically identical to the original one.  Unless I happened to get a defective one, I'm pretty certain it will work.

I just finished the installation and the good news, it works like a dream. I ordered mine from OEM BMW parts on Amazon.com. The BMW part# 16 12 1 178 035 & cost $83. Well worth it.

I have just gone through a frustrating search for a replacement for my 46 year old damper on my 78 280Z. this site below:

https://www.radiumauto.com/Fuel-Pulse-Damper-Inline-Kits-P751.aspx

Has a functional replacement that is easy to retrofit. You can also buy it at ZDepot.com online.

Just another note. I intend on installing the damper in the engine compartment instead of attaching it to the fuel pump mount. If anyone has any comments, I would love to hear them.

Not sure about mounting it that far forward upstream only for the reason Datsun did it for a reason and that was to solve a pulsating issue. Will that increase down the line I don’t know. Never have been one that might create another variable down the road IMO of course
