Leak near rear passenger wheel.

[thedandyplimsole]

Hey guys, I've had this problem on and off for maybe the last month or so. There's a drip from the rear passenger wheel, I'd noticed the kerb outside the house having the odd stain, but whenever I checked I couldn't find anything.
I've gone outside today (the car hasn't been used since yesterday) and seen this:

The leak is dripping along the route I've drawn the arrows. Would any mechanical types know of the likely cause? If I put my thinking cap on i'd guess...break fluid!

Added a video too (please ignore the phone ringing in the background):

smell of any thing?

As its dripping from the fuel filler / breather pipe i'd be giving it a good look over. If its a fuel leak you wanna sort it asap.

I've got a sneaky suspicion it could be petrol, it appears black on the tarmac, but does seem as though it could be leaking from the tank/filling area.

I remember the smell of brand new plimsole rubber

Just back from the garage, the guy couldn't bring it in and raise it up, as they were welding in there, so it was only a brief look. He asked when I last filled it up; I brimmed it yesterday afternoon.
He said that the actual pipe had started to corrode, so that if it's brimmed, any petrol left in the top half of the pipe nearest the filler cap will seep through.
His advice was simply to never fill it more than 3/4 at a time. It hasn't been leaking for the last hour or two, which would support his theory...does this seem sound to everyone?

You're nuts

Corroded filler pipe a common fault.

Agree with davyboy. It'll be corroded fuel filler pipe. You can replace it with a new one or scrapper one.

who does not agree with the davyboy is in need of mental help the whole heartedly

Shove a bit of Wrigley's sticky spearmint chewing gum down the pipe worked for Tom Cruise in Oblivion lol!

Yeah it'll be that if you've put as much as possible in. Swapping it over for a new one isn't very hard to do providing you can source a decent condition one to start with. Depending how bad the corrosion is you could also be loosing some when you're filling up.

It is a common fault though.
