Can I vapour lock a beetle?
I have a beetle that has a petrol smell. It is bad around the filler door. I have just found the inside of the filler door to have a nice round red
stain, which I am assuming to be dry petrol. I also assume that petrol is escaping under the fuel cap. Is this sounding right? I have heard that fuel
tanks need to breathe, will putting a new tight cap on allow my beetle's tank to breathe?
Thanks for any help, this game is new to me. |

Hi
the tank breaths through tubes attached to the tank, the cap needs to seal. Either buy a new cap or gasket for your old one. Also check the rubber
tube between the filler and tank, mine would weep, not drip any fuel, but it sure stank.

You should be able to buy another gasket for Your fuel cap or find something to fit under the original gasket...
If the cap breathes, its breath will smell of petrol...
Unleaded... of course....

What year is your car .... early pre 67 beetles have a small tube just below the cap you can stick a bit of fine wire through it to make sure its
clear or blow compressed air it should have a small dia rubber tube attache to allow itt ovent this should also be clear as well.

To vw54, the problem beetle is a '71.
To 68AutoBug, the cap stinks to high ... (of PULP, after learning this fact here).
Will try to find gasket/cap today.
Thanks |

On the tube between the tank and the filler neck you will find a 4 or so mm dia tube. this is the vent ensure its clear all the way through by
blowing air through it.

Sorry if I seem thick.
There is a tube as you describe. It is a meshie type tube. It seems to break off into two. One (also meshie) goes down in the fuel tank, the other
(seems to be rubber and metal ) runs up along the "firewall" and down under the fuel tank on the passenger side to somewhere unseen. I dont really
want to pull on it. I can hence find no "end". Where would one blow into any tube??
Also the main filler tube (large) smells oof fuel when you are up close to it. I can find no traces of fuel, either miost, or stain. Should this be
replaced as well? |

Get some one to listen into the filler neck of the tank to hear air comming out
