[GeeTR]

Picture dood

[shanef]

lol thats the fuel filter

[GeeTR]

LOL, i was about to say that... but figured a f.filter doesn't have a vac/boost line going to it...

[Adriano]

I think some of them have a fuel dampner, but i thought it was on the supply side. There was one on my neo.

[RB SANDY]

there is no vac line going to it but it looks like a reg and i know what a filter looks like

[GeeTR]

[neo32]

if theres no vacume going to it prob still reg just not rising rate etc i have a neo in my 32 it has one think it is aa fuel dampner

[**RB2530**]

It is the fuel supply damper...pretty sure...Looks like the stock FPR but inlet and outlet are at 90 deg to each other...no other connections to it...

I have R33 98 model GTSt and the damper is on the supply side...

It smooths out fuel flow and may also make life a bit easier on your fuel pump...

my rb20 had one. the 25 doesn't. i wouldn't be worried one way or the other.

[Bumblebee]

It is a fuel damper. not maybe.. IT IS

and they go on the return line not supply

Yep checked mine tonight and it is on the return not the supply....

[RB SANDY]

so do you need it and does fuel psi stay the same

[Bumblebee]

it dampens pulsing in the fuel lines caused by injectors opening and closing, allowing fuel to return back to tank as peacefully as possible. thats the theory anyway

[RB SANDY]

so will it be worth wile putting one on my car

[Bumblebee]

if its suppose to have one.. then yes

[RB SANDY]

can some one clear this up is it needed
