The stock 12v fuel rail is sufficiently sized for stock and moderately tuned gasoline-powered engines. With big boost or e85, the small capacity presents a flow bottleneck that may starve the engine. Stock fuel injectors and those configured to fit like stock are fully compatible. Choose our expanded Fuel Rail Fitting Kit (12V 6AN) support package, if you please. It makes integrating an FPR Adapter clean and easy. Of course, if you need "ALL the fuel", then the 8AN path is there for you, too.
Note: Use our "BIG Bore" Fuel Rail Fitting Kit" to make plumbing this rail clean and easy.
