Hey everyone -

 

I have a 2006 Impreza wagon. Last oil change, the mechanic brought me over and pointed out this circular piece. Said it was leaking fuel, but that it might be easy to fix myself.

 

My problem - I have no idea what it's called, where to find it and if it's safe to fix myself. I'm worried about any pressure build-up, etc. Any ideas?

 

Thanks in advance for the help!

I’ve never seen those leak, is that an outlier or certain year thing?

 

could it be a hose connection?

 

If they’re pricey, I wouldn’t hesitate to install a used one, they don’t have any measurable failure rate unless it’s some specific year model thing I don’t know about.

Pretty sure I have read 2 or 3 instances of those leaking. Not common - though perhaps as these cars age we will see this more often?

Ethanol in the gas degrades the rubber diaphragm seals inside. This will become very common as we see these cars getting older.

There is no rubber in those. It's just an open expansion chamber. 

 

Also - pretty much all fuel systems today use neoprene based components that are impervious to Ethanol.
