Show original supplier description
This is particularly useful during fuel system upgrades, such as the installation of larger injectors, fuel rails, or new fuel lines, and is a standard component when using IAG billet fuel rails. Constructed from a single piece of 6061 aluminum, this adapter features an o-ring inlet that is converted to a 3/8 inch OD hose barb. It retains the stock fuel line outlet and includes a ¼ inch hole, enabling universal mounting flexibility within the engine bay using a single 6mm bolt. The adapter is manufactured in IAG's facility in Westminster, Maryland, and comes complete with zinc-coated steel hardware. Please note that the FPR and quick disconnect shown in product images are for illustrative purposes only and are not included with this adapter.
