Chevy 360 Swivel Filler Neck - Clear

The Chevy 360 Swivel Filler Neck - Clear by CSR Performance is a precision fuel system component designed for street and performance vehicles requiring reliable, efficient fuel fill geometry. This swivel filler neck eliminates problematic fuel sloshing and overfill conditions that plague aggressive driving, cornering, and acceleration scenarios. Whether you're upgrading a classic Chevy or modernizing a fuel system during an engine swap, this clear design provides both functional integrity and visibility into your fuel delivery path.

Manufactured from durable clear material, the 360-degree swivel design allows the filler neck to articulate freely, adapting to vehicle motion and preventing fuel backup into the overflow tube during hard acceleration or cornering loads. The clear construction enables visual inspection of fuel level and fuel quality at a glance, while the 4.25-inch dimensions provide a compact footprint suitable for tight engine bay installations. CSR Performance's engineering ensures compatibility with fuel caps and tank openings across Chevy platforms, while the lightweight 1.08-pound design minimizes parasitic weight and vibration concerns common in aftermarket fuel systems.

Enthusiasts performing engine swaps, fuel system relocations, or high-performance modifications will find this filler neck essential for reducing fuel surge and maintaining consistent fuel delivery during sustained acceleration or road racing. The swivel design is particularly valuable in vehicles modified with aggressive suspension geometry or those routinely experiencing lateral G-forces that destabilize traditional fixed filler necks. Installation pairs seamlessly with CSR Performance fuel cells and OEM Chevy tank setups, making it an ideal choice for builders seeking OEM-quality reliability with aftermarket performance benefits and long-term visibility into fuel system health.
