I do know that at the QB factory they have what looks like a spa bath where the finished tank is actually submerged in for testing. So theoretically it should come to the customer leak free.

Having just finished a build where I tested the tanks in various ways however found the bullet proof way was to fill it full of fuel, leave and see what happens. The reason fuel is the way to go is that the blue staining makes it easy to see a leak or weeping rivet.

Default QB Tanks

Thanks for all the responses. I believe I will leave the tanks in place and perform the leak tests. If one is identified then I will remove them to identify the leak.

Thanks again.

Review my thread where I cut open my QB RV-9A tanks and modified them to increase the capacity by 3.5 gallons per side. Not happy with what I found and not at all surprised so many develop leaks.
