What is that bottle above the rear passenger tire do? If its a windshield wash bottle or something stupid, its coming off.

WTF are you talking about?... do you mean the battery cover in the trunk?

No man, I found a bottle that looks like either a coolant reservoir or a windshield wash bottle up in the wheel well of my passenger side rear tire. WTF indeed.

Pics? Where do the hoses go?

[T.Dot E30]

it has 3 hoses attached to it, and i think they are to vent the gas line going to the tank or something.

Yeah it seems like that. But why would there eb a bottle there?

[mikeedler]

i believe it is an expansion tank for the fuel tank.

Correct.

Leave it alone.

[Streetspec_iS]

just imagine its NOS

It's a source for rust holes to start. I filled a ton of holes in that wheel well because of all of the screws holding in the expansion tank and fuel lines. what a mess.

[turnofftheradio]

do you really need an expansion tank? you got me thinking that may be my gas leak. I have to pull the tank anyways, but it seems to be the affected area.

[89_325i]

Yeah, its a vapor recovery tank or some such. I just got a service manual. Major rust producer though.
