BR600s leaking again

Hey guys,
Got a br600 magnum and an older br600 that is leaking around the top of the gas tank. It leaks after every time I use them but the leak doesn't seem to come from the engine. I took the magnum to the dealer and they gave it a going over with a new fuel cap. Since then the leak has come back and is getting worse. All fuel lines are new. Any ideas on what it could be?

Mine did too. Just had to do with the cap not being seated right. Sounds easy, but its a poor design.

Check the seal in the cap. If you go to tight you can tear them.

My 420 has a breather device fitting into the tank and tube going up to intake of carb and that can leak.

May just go get a new seal. Seems like a lot of people are having the same problem. Thanks for the replies.

Mine leaked for a long time...
Many things went past...

Until one day...

*I* cleaned mine up real nice and good as *I* took it all apart.
Then, *I* inspected everything carefully and found a cracked fuel line and *I* replaced both the fuel lines.
Last but not least *I* put it all back together real nice and slow, making sure *I* got all the parts back together exactly the way they were supposed to go.

No More Leak.

I didn't think about this earlier, and I do highly recommend getting the new gas cap but also check the primer bulb.

Thanks. I have replaced all the fuel lines twice and the primer bulb and of course the cap. The only thing that I have not replaced is the gas tank seal connector and the crankcase supply hose. Well see what happens.
