72in #4 Line -4 Str/-4 Str 5pk

The 72in #4 Line -4 Str/-4 Str 5pk by Allstar Performance represents essential braided stainless steel hose line assembly for serious engine builders and high-performance automotive projects. Whether you're assembling a custom fuel system, transmission cooler circuit, or precision coolant loop, this five-pack bundle delivers the professional-grade hose lines that competitive mechanics and dedicated enthusiasts trust for reliability under demanding conditions. These pre-assembled lines eliminate guesswork in critical fluid delivery systems where thread fitment precision and durability directly impact performance and safety.

Each line in this bundle measures 72 inches end-to-end, featuring -4 AN (male) straight fittings on both ends, making them compatible with standard -4 AN port configurations throughout your system. The #4 designation refers to the 1/4-inch nominal ID (internal diameter), sized appropriately for moderate flow applications like fuel returns, auxiliary cooling circuits, or low-pressure transmission lines. Constructed from professional-grade braided stainless steel with properly swaged fittings, these hoses resist vibration fatigue, maintain thread integrity through thermal cycling, and deliver the consistent performance expected in race-proven and street-performance environments. The five-pack format ensures you have spares for assembly iterations or future modifications without additional shipping costs.

Competition-level engine builds, vintage hot rod restorations, and custom cooling or fuel system installations benefit most from this proven Allstar Performance solution. The straight -4/-4 configuration simplifies installation in engine bays where tight tolerances demand direct line routing without 90-degree adapters. Installation typically involves hand-tightening the AN fittings to your ports and securing the hose line with factory clamps or dedicated hose separators to prevent abrasion against block, headers, or frame components. These lines are compatible with any system using standard AN -4 male ports, from carbureted fuel delivery to modern EFI returnless systems, making them an indispensable addition to any serious builder's inventory.
