Frequently Asked Questions
Does this neck require any prep work before welding?
Clean the mounting area on your fuel cell with a wire brush to remove any oil or mill scale before welding. The neck itself arrives ready to weld — no additional machining or coating needed.
Can I use this with an aftermarket fuel cell overflow or vent system?
Yes. The aluminum cap is straightforward to drill or machine if you need to plumb a secondary vent line or overflow return. Work out your fuel system layout before final welding so you know exactly where to open it.
Will the 45-degree angle fit my engine bay layout?
The angle is designed to clear headers and tight installations where a vertical neck doesn't work. Measure your available space and test-fit before committing the neck to the cell — engine bay geometry varies significantly between builds.
