EVIL ENERGY 6AN Male to 5/16\" Hardline Compression Fitting Adapter Aluminum Black – 2 Pack

EVIL ENERGY 6AN to 5/16 inch Hardline Adapter (Aluminum Black) – Two Pack

When upgrading a fuel delivery or engine management system, reliable fittings can make a meaningful difference without complicating installation. This EVIL ENERGY adapter connects a 6AN male flare to a 5/16 inch hardline, delivering a compact, corrosion resistant option for tight engine bays and performance builds. The black anodized aluminum finish adds a sleek look while offering resistance to heat and fuels in everyday use.
