NB here. Hello all. I have a few pix of a part that needs to be replaced in the fuel system area. Not sure how to post the pix.

After the pix are posted I'll need the name of the part. Ty

Fuel system "area" is almost the whole car because it goes back to front of the car.

Host the picture on imageshack.us or photobucket.

Next time, name the thread title related to your topic.

Hello Again,
This is the part I am looking for. It appears to be a Fuel Pressure Regulator, but I'm not sure.

looking at your engine from the front....your fuel pressure regulator is on the left front side of fuel rail.

your fuel damper is on the right rear fuel rail near the pcv valve and it has a screw on the top

Thank you for your reply. What symptoms or signs would you have if the damper is going or has gone bad?

I found this on the web for you

The damper smooths pulsations in fuel pressure that occur when the injectors fire. The amount of pulsation and the related pressure drop through the system vary with the duty cycle of the injectors, with minimal need at idle and more need as engine load goes up.

I located a Fuel Damper Assembly at Napa for $45 (echlin fuel systems) and on Amazon Auto for $56 (Borg Warner 32501). Anyone have any experience with these parts?

Update: The Napa (Echlin Fuel System) part was the wrong fit.
