Pulsation damper failed....

Hi, I thought I'd put in my two cents. It's sad to see the pics, but it doesn't look too badly off. Good luck with the repairs.
One other thing concerning Fire extinguishers: avoid the First Alert units. They discharge this horrible green powdery stuff that gets everywhere.
No, I didn't have a fire in my RX7, I replaced my three-year-old First Alert Auto with a 5 Pound Amerex Halotron.
Before I disposed of the old extinguisher, I depressurized it by discharging it. This isn't something I'd want to repeat indoors. Halotron is much better for a automobile because it dissapates quickly and leaves no residue. Not to mention that you can actually see what you're extinguishing (so I've heard).

Don't forget how to properly mount it (NSX-centric, but it gives you a good idea of what to do):

As for the aftermarket retrofit, it's not any more complicated than it would be to pull off the top intake to get at the stock FPD.
The drawbacks to this conversion are that it's more expensive than simply replacing the stock FPD, and if you use cheap fittings (such as I did at first with a cheap t-fitting that didn't have the correct flared ends) you will get leaks.
Fortunately, any leaks are further away from the exhaust manifold, so there's less risk of a fire. Also, there is a clearance issue between the aftermarket fittings on the secondary fuel rail and the upper heater hose, but I haven't run into any problems with that.
However, what you get is a safer (theoretically) setup since if the after market unit fails, it won't leak, the unit is rebuildable, and if there are leaks, there isn't a bigger risk of a fire.
But don't let that be an excuse to not fix a fuel leak! Gasoline is a flammable liquid, and if there are leaks, fix them immediately; I do.

I came across a discussion about putting 89 - 91 model PDs on an 86-88 car. Explain to me what the advantages of this later PD are over the stock 86-88 model PDs if any. I realize that the PD is attached but that doesnt necessarily mean it wont leak will it? Are they just made better?

I bought a 90 camry v6 for my dad, with 110k miles,
2 months with little driving the pd failed, the small screw just backed up and it was seeping gas, it was 7 F that week back in December, I drove it back 150 miles all hwy after I found it in Novi, MI, the part was a denso part, for the toyota, $80 or something ridiculous like that.
Aaron, how do I tell if the PD on my vert was changed at some point in its life?

i guess im a lucky one that had pd failure i pulled into the house after driving around popped my hood to take a look cus i smelled gas right after i lifted it whoa fire ran grabbed the fire extinguisher while cutting the car off and put it out took less than 30 seconds only damage new upper radiator hose and omp lines and of course pd intake mani gaskets (and egr block off plate and rats nest removal so vacuum hosing and fuel line and coolant line)
but im sorry for your loss but this informs alot of people about the dangers of old (rubbers) and parts. dont take that rubbers part perverted i mean like hoses and internals. and hopefully you will be able to get her right easily

How do you guys feel about the removal of the PD. I did this n my 87 and have never had any noticable problems.. My 88 is parked right now and I did smell a faint odor of fuel when I replaced some vacuum lines.. I think I will be removing that on as well...However Aaron I am interested in what you said about the Denso part being fairly common on many cars like the s2000.. Gonna look the part up on ebay and see if the thread size is a match..

wow, looks like I'll be checkin mine.... The car had fuel leaks, which I have since situated. Unfortunately I smell gas now when shifting, I thought it was due to boost leak (which I have hopefully fixed..) Damn I wish this post would have happened a couple days earlier when I had the UIM off

Until you bring up objective proof, stop guessing what the hell is wrong.

I'm glad this repost came up because I think mine is failing. It's in the garage getting some intake work done but the gas smell just started two weeks ago. I was out swinging the back end out and getting the tach all over the place and I smelled gas for miles. I thought it might be the gas filler neck but now I heard about this and I took a look. Mine has residue and dirt all around it. An interesting thing I noticed about it is it's similarity to a part in my Protege5. Sure enough it is the analogous device on that fuel rail and I'm looking for a cheap deal on one. It screws out and everything
