Simple installation:

*Sealing is important in this application. We don't trust AN fittings on their own. We know you have anecdotal evidence that they've never leaked on your race car or aircraft, but in our experience, they are hit or miss, and we can't have a miss when there's fuel strapped to your back. A soft copper flared seal is a cheap and easy way to ensure that no matter what, your fitting will be sealed.

You may have seen an outdated flyer included with your flamethrower that incorrectly mentions the backpack kit including a larger battery. This kit does not include a larger battery. We have yet to find a source of larger batteries we can readily obtain in high quantities, and the price reflects the non-inclusion of the battery. When we can stock bigger batteries, we'll add it as an optional accessory to the kit in the future.
