I looked into that, even made a post about it.
After emailing the seller I was told that the common application for this part was carbed return-less aircraft engines.
And the problem its intended to prevent/fix is described on that page its not an issue you would have with a car.

stupid people do stupid things. like buy pieces of **** like this. you can buy a fuel pressure regulator with a built in pd. you could eliminate it with a banjo bolt, or swap over for a s5 primary fuel rail, or buy a replacement(expensive).
all of these sound better than " a ball filled with air "

Isn't a custom Marin FPD the only alterntive that really works? I have an S5 that I bought with a JB welded FPD since it had begun leaking during it's previous ownership.
I'll need to take care of this eventually. as I do believe it should be functioning and on the car.

i was just considering a marin the other day, I don't see why it wouldn't work if it was sized right and you managed to get the fittings to run it in line after the rail. I have also heard that some aftermarket FPR's have pulsation dampers built in or act as one by their nature.
Does the Aeromotive A1000-6 act as a pulsation damper as well as a fuel pressure regulator? I am looking for an aftermarket FPR already so if I can kill two birds with one stone that would be great.

Talk about PMS-ing. You need to chill out a little before posting rubbish. Speaking of stupid, re-read your post.
Everyone's an engineer here, I guess. A bolt is better than a fire, but why not just spend some money on a brand new direct replacement FPD instead of throwing it on other ****.

My personal thoughts is that any setup with large injectors (1600CC) needs a pulsation damper. However currently, I am not running a damper on my setup as I just plain forgot to plumb one in. It's on my list of things to do before I raise the boost, though.
Almost every EFI setup (besides some of the modern returnless systems) includes a pulsation damper, so regardless of what people say, there is obviously a big enough need for the auto manufacturers to include them on virtually every EFI car.
Now whether or not removal of the pulsation damper will actually cause problems on a stock car is another question entirely. It doesn't seem to be an issue, though that is likely due to the fact that the stock tune is pretty rich and any fuel delivery hiccups caused by damper removal are far less of an issue.

^ Well said.
I (as in not necessarily coming from the above) would say the PD matters enough to spend the money on a replacement PD - not a banjo bolt - every several tens of thousands of miles. But it doesn't matter so much that you can't get away with a banjo bolt. And both are better than an engine that's on fire.
And since a good PD is pretty cheap, considering how long it lasts, I have no idea why anyone would gamble their car on something else like this $47 unit.

Dont FP regulators like an aeromotive for example have a PD built in? I have heard that but I am not sure. Oh, need to read already mentioned earlier in the thread
