GFB FX-D Low Pressure Fuel Regulator - Universal
GFB has built its reputation on precision fuel and boost control components for performance applications, and the FX-D continues that focus with a purpose built solution for carburettor setups running an EFI style fuel pump. It's designed to bring high pump pressure down to a level the carby can actually use, without sacrificing flow or response.
This listing covers the GFB FX-D Low Pressure Fuel Regulator, SKU 8070-LP, a universal fit unit suited to any carburetted engine fed by an EFI type pump. As a single variant product there's nothing to select on the listing page beyond adding it to your build.
Note: The FX-D is a low pressure bypass regulator built specifically for carburettor applications — it is not intended for direct EFI injector feed systems.
