EFI Fuel Line Kit Holley 4500 Stealth

The FRAGOLA EFI Fuel Line Kit for Holley 4500 Stealth delivers the precise fuel delivery architecture required for modern electronic fuel injection conversions and high-performance carbureted applications. This braided stainless steel fuel line assembly connects directly to Holley 4500 throttle bodies, accommodating dual 3/4-16 inch male O-ring outlet ports while accepting an 8 AN male inlet connection, ensuring proper fuel flow routing from pump to injector rails without leakage or flow restriction.

The kit features braided stainless steel hose construction paired with black anodized aluminum fittings, a combination that resists corrosion from fuel contact and engine bay humidity while maintaining pressure integrity across fuel system demand cycles. The O-ring sealed ports prevent fuel seepage at connection points—critical for meeting EPA fuel vapor containment regulations and maintaining consistent fuel pressure in EFI systems where even minor leaks degrade idle quality and cold-start performance. The dual outlet configuration allows independent circuit control or balanced distribution to dual fuel rails in divided-plenum applications.

This kit addresses builders converting carbureted or older TPI engines to Holley 4500 EFI platforms, where OEM fuel line assemblies either don't exist or require custom fabrication. Weighing just 0.69 pounds and measuring 13.25 inches in length, the assembly integrates into engine bays with tight packaging constraints common to modern engine swaps and retrofit builds.

FRAGOLA specializes in high-pressure fuel system components engineered to withstand repeated thermal cycling and fuel system pressure spikes inherent in performance applications, making this kit a reliability-first choice for builders prioritizing longevity over cost-cutting alternatives.
