Ok, so I am planning to install the Walbro 255 LPH fuel pump soon and I was doing my research as I always do before I jump into a project. I came across something interesting today. Before removing the fuel lines the fuel pressure must be relieved. According to the helm manual it says to loosen the fuel pulsation damper one complete turn to relieve the fuel pressure. Now it also says that if you do that, the washers to the fuel pulsation damper must be replaced. So I go to Majestic Honda's website to look up the part number of the washer. I have an 05 MY S2000 so I plug that info into the Auto Parts Section on the website. I pulled up the (intake manifold) system/component section up. There is no fuel pulsation damper in sight. I check around in the other system/componenet sections but no dice. I took a trip to my local Honda dealership and tell them that I am looking for this washer. They ask "what year is your car?" so I say 2005. They have the same pics as the Majestic Honda website. The parts guy said what he thought was the part but it didn't look like it to me so I didn't order it. So I came home and did some more research and this is what I found:

If you go to to the honda dealership or are looking up parts @ the Majestic Honda website for the fuel pulsation damper or its washer you must plug in 2006 MY S2000 and up, then look in the (intake manifold) system/component and you will find the fuel pulsation damper and its washer regardless of what MY S2000 you have.

Fuel Pulsation Damper Part # 16680-PZX-003

Washer for fuel pulsation damper Part # 16705-PD1-003

I hope this helps others.

*****EDIT******
After the reply below and help from JFUSION, if you search your Model Year and go to (Fuel Pipe) system/component you will find the fuel pulsation damper and its 2 washers.

The other washer that I failed to mention above(also needed for the fuel pulsation damper) is Part # 90428-PD6-003

Ok, I guess I missed that one. Thanks

I've had mine off about 50 times. I have replaced the washer once when it started leaking about 5 years ago. Consider keeping the new one for later and continue to use the original.

I used a crush washer for the oil pan... worked fine.

My question, those who plan to install aftermarket fuel rails. Is it really necessary to even have the pulsation dampener? I know what it does an it's purpose. But do we really need it of your planning to put more pressure or more fuel to the engine? Will it be beneficial then?
