Fuel Pulse Damper Question

Fuel Pulse Damper Question
In the Supra MkIV TT world, removing the fuel pulse damper, located between the filter and rail, is considered an important modification, removing a restriction in the fuel line. PHR offers a line for this (https://www.powerhouseracing.com/pro...-1993-98-supra). Radium, a popular S2000 vendor, make their own fuel pulsation damper (Blog Post New Product Release: Radium Fuel Pulse Dampers) and makes a kit to replace the Supra's FPD with their own. They sell a complete Supra fuel system from in-tank pump hanger to the fuel rail, leading me to believe someone there owns one.
However, I never see it mentioned here. Is that because the rail mounted OEM version is fine? Is that because it is discarded and no one sees a benefit in keeping it?
Thanks,
David

The good news is that if you are doing aftermarket fuel lines and you end up using rubber line braided line they tend to absorb a ton of it.

This video showed up in my e-mail:Pro Tuner Tip - Fuel Pulsation Dampers Radium Engineering
When upgrading the fuel system, a component that’s often overlooked is the fuel pulsation damper. You’ll usually find these fitted to the factory fuel rails by the OE manufacturer, but they are often thrown away when fitting aftermarket fuel rails.

I agree with the overall theory. You want a good larg uel dampeners and a large bore fuel rail to help absorb injector open and close pulses. Adding a larger fuel damper and increasing fuel rail size will mak the injectors 'click' less they will run less noisy. Think of opening a watter faucet quickly and the 'thunk' it makes when it first open or closes quickly same principl applies

In my opinion the radium fuel rail which is the largest for s2k is the best, if you can reuse the stock fuel damper AND an iridium fuel pulse dampener aswell that would significantly quiet down on injector noise associated with rapid fluid pressure changes
