Strong Fuel smell inside....urgent help needed!!!

[gor131-x]

Ive been getting a really strong smell of raw unburnt fuel inside th car,yesterday it got so bad that i had to pull over,switch car off,open all doors and stand outside until it was breathable.
 any idea what it could be,ive bought oil filter,fuel filter spark plugs and oil to get it serviced but i want to sort this problem out, if any before i do the service.

oh and the fuel economy is crap,20 quid gets me just about to a 100 miles

ive had a look at the engine and i noticed a pipe disconnected,what is this?
and also i did a search and some guys said the coolant sensor is a blue type thing at the front,i havent gota   blue one,ive got a yellow one and a blank,is that right?

car is a 1.4 AEX engine code

Pics

whats this?the pic is from under the airbox at the back and has it got anything to do   with my fuel smell problem?


and is this suppsoed to have a blank next to the yellow sensor (by the way,whats that one for?)



any help appreciated and im not driving the car until this smell is sorted,

thanks

Fuel leak some where.

Genius.

You are a genuis.

Are you experiencing any running issues? Along with the smell?

Fuel leak some where.

yeah i figured that part out

it runs fine,the idle sits at 600rpm and you have to give it a bit of throttle before setting off or you'll just stall it but it is only a 1.4 so im thinking thats normal

apart from that,its drinking a lot,like i said,i put in £20 and im on 82 miles and im halfway into reserve

  You need to follow your fuel line from the tank to the engine and find that leak and be carefull petrol is really dodgy stuff. Sorry you already know that.

if you have difficulty seeing then use a lighter. Make sure you hold it close to your face to get the most visibility

Is that pipe in the first pic a crankcase breather pipe?
Split or disconnected crankcase ventilation hoses can cause fuel smells in the cabin.

Long shot but maybe the tank sender seal has let go.

agree, sort that busted pipe out and see if it still smells

As mentioned before, this is your most likely culprit, in my experience, the mark3 is very sensitive to breathing issues, replace this hose and take it from there.
