What Is This Fuel System Component

Hi all,

Putting a 25 in my S13 and I think i left this on the now disposed halfcut. It sits in between the return from the fuel rail and the tank on R33's.

FAST describes it as a DAMPER ASSY. Do I need it?

Cheers,

Agree...you don't need it.....but!

It does serve a purpose. Nissan put it there for a reason but it's not critical to engine running.

Cheers fellas

Anyone know its original purpose...just out of curiosity?

Fuel line, pressure oscillation dampener?

[The Dan]

Stops pulsation of fuel returning to the tank caused by injector pulse at high pressure. The FPR, to regulate fuel pressure, pulses because of the injectors and therefore the dampener was added to prevent cavitating etc.

yes, and a ticking/banging noise that runs down the fuel line....
