What part is this?
 

I just pulled my rear seats out for an upcoming time attack day and under the bench seat in the rear there's a part that I can't figure out:

Anyone know what this is? Best suggestion yet is fuel tank access or float switch.

do you have the tech package? maybe it's something to do with the bose system

No i've got the base model. And the sub woofer sits in the spare with the tech package.

yeah i know that...was just wondering...download the shop manuals in the VIP section...i'm downloading them now because this got me wondering haha i have no idea what it could be

Fuel tank access? Or pressure sensor for back seat passengers?

Sorry I didn't fully read your first post.

in my old subaru something that looked similar to that was for the fuel pump/float switch.

I am reading through the workshop manual as we speak. needle in a haystack tho.

You mean the black cover? That's the access cover for your in-tank fuel pump?

01-14b-10 of your service manual...it's the cover that gets you access to your in tank fuel pump unit.

Sweet, learn a new lesson every day =)

Fun stuff eh, I had to replace a lot of fuel pumps @ work. Stupid BMW is notorious for both their HPFP and their in tank pumps.

You're all wrong. Its the canooter valve access port. Very important piece and very delicate.

You mean this?
