Had my gt200 for 2 weeks the last few days there has been either a loud or quiet sucking vacuum noise from the left rear wheel arch area. Any ideas everyone. It happens when I'm driving and also when engine is off and parked up . When parked up it still sometimes does it after a while. Curious. Thanks john

Possibly fuel tank breather? Just a stab in the dark I’ve never heard of that before 🤔

What happens when you hear the noise and open fuel filler cap?
Does it then stop making the noise (until the next time)?

When it's left overnight it sometimes still hissing away the next day. Well try fuel cap and see what happens. Going into garage tomorrow as it's under warranty. Cheers.

Fuel tank Vacuum ? When you open the fuel cap it will sometimes make a "Whoosh noise" as it sucks air into the tank as has been suggested by neilgsxr69 you may have a fuel breather issue & as all fuel systems are pressurised its a slight possibility it could have a cracked fuel hose sucking in air somewhere
