is that right on the fuel fuel pump because i think i know what your talking about if it is Thanks for the picture!!!

sorry bout that

It's mounted on the fuel pump with a bracket that looks like a small motor mount.

ok the persone before me must have put a in_line filter there if that damper didnt work would it cause it not to start( lack of fuel?)

I've never heard of a damper going bad. I'm going to give you this link. It's the 280Z Fuel Injection Book. It will answer a lot of your questions. You'll need an Acrobat reader and if you have dial up.....well it's over 70 pages. Save it to your computer. It'll answer a lot of your questions.
