Yep I've seen it happen all the time. I always seal new tanks to be sure,

Did you pressure test it first? Just because its new doesn't mean it won't leak.

The whole sight glass thing always seemed like an accident waiting to happen. Rip the tubing and you'll have a serious leak then...or I could be wrong.

when i got the tank it came with a paper that said it was pressure tested but i got a buddy who can do that for me it just pisses me off that this company sucks ass in my opinion now and needed to rant and as far as the sight glass goes i live in a very rural area so odometer and or sight glass is almost a must for me and im not too hip to throwing kreem tank sealer in a new tank i have seen it do some gnarly stuff to carbs and petcocks so i think a little brazing and tig welding is in the new tanks furure

Be glad you didn't have a high dollar paint job. Use POR 15 in the tank you will be glad you did. Even with welding it you won't be sure.

Always pressure test tanks.

I take mine to a radiator shop for Red Cote before use.

Never bed line a motorbike.

Sorry to see you experienced problems, but yours is a perfect example of why every tank should be pressure tested before being put into service. The test can be as simple as using a plastic bag for a gasket between the cap and the tank and then putting air pressure thru the petcock while spraying a soap and water solution on the tank as you look for bubbles . Obviously you want to pay particular attention to the welds or places where the metal may have been streched thin during the forming process. You want to use a regulator so you can accurately controll the air pressure. A few pounds pressure is plenty, and will reveal any leaks. In fact, if you venture beyond 10 psi you run the very real possibility of deforming or distorting your tank. Not good!! :eek:.

An alternative to the soap test on the outside of the tank is a hydro test. A hydro test is performed by in a similar fashion but you fill the tank with water before applying air pressure, and then look for for signs of seeping thru the tank. Once again, keep your pressure in the single digits when testing gas tanks. Back in my days of building refineries and chemical plants we always hydro tested critical piping systems but we tested under much higher pressure. Good Luck to you in the future.

Regards,
Geo.
