Get that fixed correctly before you light yourself up.

 

+1 on the fix it now sentiment. In the worst scenario, you could spit a fuel line loose, or split a seam and go up in flames.

Another scenario is that it could leave you with a fuel starvation problem. If the tank can't relieve built up pressure, then it also means that air can't get back in to replace used fuel.

Sometimes this happens in cars too when people top off the tank so often that the charcoal cannister fills up and clogs. In a car, you can leave the cap loose until you can get top the garage. I wouldn't wan't to try that with the gas cap between my knees, so you'd have to stop every couple of miles to vent the tank as you limped home.

 

First make sure you have the correct cap for your tank, not all caps are vented. If the cap is ok then drain the tank, remove the tank, use a hand drill or a yankey( push pull ) drill or like stated before, a drill in a tap handle and drill out the vent line by hand. carefull, sparks here are not the desired effect, replace the tank, replace the vent line on yer scooter, refill with fuel, 1/4 tank will do, go for a ride and see if you still have the same problem.

 

yea, let the tank air dry out for a day or two, then, go see a welder who has a argon tank. Flood it with argon, cap it off, (just to keep it in), you can't blow it up. Argon will not burn. I do tank repairs from time to time, that's how it's done. Hope this will help.

+1. Petrol (gasoline) isnt realy that easy to ignite without a wick (not that I suggest you try), but the fumes are a different matter altogether. Just because you've drained the tank dont think its safe to start using power tools because your potentially working on a very explosive device.

I used to work for a large oil company and removal of the old underground tanks at the filling stations was one of the most dangerous activities they undertook.

Take Hollywoods advice. Better still, if you cant get a replacement cap take it to someone who specialises in doing tank work of this nature.

Stay safe.
