Guys, i have a 2006 GS430 with around 119k miles...Last night when i started the car and turned on the Fan, Strong Gas smell started to seep in through the Vents, At first i didn't really think much off the smell...Drove home (about 2 miles) and then Opened the hood while car still running.

There is this black round piece that sits on the Fuel pressure line (Or atleast that's what it seems) it's completely soaked in GAS (Petrol), i need to know what this part is called.

Is it Fuel Pressure regulator? if it's fuel pressure regulator is it easy to replace?

Here is the picture that was just taken (Upon starting the car)

Will really appreciate all your help.

Anyone? Does this look like a Fuel Pressure Regulator or a Fuel Damper?
I would appreciate your guys input before i order the part.

It looks like the fuel pressure regulator to me when I did a Google search. I bet the rubber O ring is bad. I'm not sure about the install but I bet you would have relieve the fuel pressure first. Maybe take it to a dealer and let them diagnose it first before swapping out parts. Let them do it if the price for part and labor is reasonable

Thanks for your feedback...Doesn't look like a difficult task to handle other than letting out pressure before taking the regulator out.

What's weird is that i drove the car quite a bit yesterday evening and today but the fuel pressure regulator seems normal & dry, quite possible that rubber O ring is not fully deteriorated.

I am going to call stealership tomorrow and order the part anyways.
