Title: Bloody Golf!!
Post by: Sir Tigger KC on 08 October 2011, 21:23:21

When I take the fuelcap off it hisses as a vacuum has built up.  It's got much worse today though.....

I'm going along quite nicely, when it splutters like it's out of fuel, but there's plenty.  So I stop, have a look and there's fuel leaking out the back!! I loosened off the fuel cap and fuel sprayed out!!  :o  There was a massive vacuum built up in the tank and I could hear things relaxing as the pressure was released... :(

It must be a blocked breather, but I don't know where to start!  There's a nozzle just in side the fuel pipe that can be wiggled!!

Any ideas??  :-\ ::)

If fuel sprayed out then its not a vacumn that you have  ???

As you say, it's a blocked breather/vent. Not sure what age of Golf but normally attaches high up on the tank, sometimes near the pump/sender. May well be a corrugated plastic pipe ;)

taken from a vw forum a bloke on there has same problem and this cured it

There is a "breather" tube which vents behind the plastic liner in the rear offside wheelarch. You need to remove the liner, easy job provided you have the "Torx" attachments for a screwdriver. Locate the tube and ensure it is not kinked, you can use a straightened out metal coater hanger to poke out any dirt. That should sort the matter out.

Thanks Millwall.  I found another thread on the ClubGTI forum where two pipes were connected incorrectly into the purge canister.... It's abit vague tho... :-\

The symptoms are exactly the same.  I let it tick over today with the fuel cap off and fuel started welling up the pipe till it was spilling out!!  :(
