Petrol smell from my 2005 BA Falcon

[arm79]

If its a sedan the likely first place to start is the short rubber hose that connects the filler pipe to the tank itself. They are randomly starting to perish and start to leak fumes and eventually to leak fuel itself.

I've replaced both hoses on my and Dad's BF. Dad's was bad, it looked like someone had taken a stanley knife to it, cutting slits along the length and was leaking fuel. Mine you could smell a faint fuel smell under the car on a hot day and only when you really squeezed the hose hard once removed could you see any sign of damage.



If it is that, good luck finding one. They are very rare at the moment, rare as rocking horse ****. Doesn't help that the assholes at Ford decided to make the filler pipe and tank inlet different sizes, so you cant even used some standard hose to do the job.

Worst case you might have a crack in the tank or a seam where a fitting protrudes from the tank. Apparently this was pretty common at one point, tanks failing under warranty.



The join around the 2 white circles on the left of the tank fail and fuel and vapour and fuel can leak from there. You don't want it to be this because you need to take the cradle out to get the tank out.

The carbon canister is under the raised section of the boot floor, right behind the seats. It's just off the drivers side of centre. You need to jack the car up and get in there with a light as its wedged up deep between the floor, cradle and fuel tank.

Start with the fuel filler hose, cross your fingers and hope its that.

Thanks for coming back to me with so much detail & Pics. If I keep my tank at half full or below, I don't have a problem with the petrol fumes. I accidentally filled up to three quarters two days ago & the petrol fumes filled my garage & came into my house so pretty strong! If the smell from the fumes came back with the tank at three quarters full, is it more likely to be from tank than the rubber hose to the filler pipe.

Id still check out the hose.

In Dad's case it only smelt after he filled the tank and for the next few days. The smell got progressively worse as time went on until one day you could smell it 10 feet from the car. Looking underneath is when I first say fuel dripping from the hose.

The rubber hose is easy to access. Get on your back and look up under the bumper, it's in full view. Grab the hose and squeeze it a few times. See if you are any indications of perishing. Also smell your hand after, if it smells of fuel it's that.

I've also read of failures in the seam where the tank inlet meets the tank. So look for leaks from there.

Also investigate T3rminator idea. The fuel pump is sealed to the tank by a weird design seal. As you can see in the pic, at a certain point, half a tank or more, the entire bottom half of the tank is filled to the brim. Any failure of this seal when the tank is filled past half will instantly show a leak.

Really appreciate your advice. Thank you
