Filler Hose 2.25in ID x 5ft

The Filler Hose 2.25in ID x 5ft from ALLSTAR PERFORMANCE is a critical fluid transfer component designed for engine builders, restoration shops, and serious DIY mechanics who demand reliable coolant and reservoir plumbing. This hose is engineered to handle high-temperature fluid dynamics in custom cooling systems, fuel cell setups, and modified engine bays where stock routing won't accommodate your build. Whether you're fabricating a custom cooling circuit or upgrading a vintage engine to modern specifications, this 5-foot length gives you the flexibility to run lines exactly where you need them without unnecessary splices or weak points.

Built with a 2.25-inch inner diameter, this hose accommodates substantial flow rates essential for high-horsepower cooling systems where undersized piping would create bottlenecks and restrict thermal transfer. The 5-foot straight length eliminates the pressure loss and kinking issues common with coiled or segmented hose assemblies, allowing coolant to move freely from radiator to engine block or between custom reservoir tanks. ALLSTAR PERFORMANCE's construction focuses on reinforced walls that resist collapse under vacuum and maintain structural integrity across repeated thermal cycling—critical when running aggressive coolants or pressurized systems in race or high-performance applications.

This hose is ideal for builders working with LS swaps, custom cooling loops, fuel cell installations, and modified water pump configurations where OEM hose routes are incompatible or insufficient. The generous diameter makes it compatible with most aftermarket water pump outlets and overflow tank connections found in performance builds. Installation requires basic clamp work—use quality hose clamps rated for the operating pressure of your system to ensure dependable sealing and prevent leaks during extended track days or street driving. Available by the 5-foot length, it provides enough material for most single-circuit applications while remaining cost-effective for builders who need to experiment with routing before final assembly.
