GM Style Chrome Oil Fill Tube & Cap

The GM Style Chrome Oil Fill Tube & Cap from Edelbrock is a direct-fit replacement solution designed for serious engine builders and mechanics restoring or modifying GM intake manifold applications. This chrome-finished component replaces factory or deteriorated oil filler tubes on small-block and big-block Chevy engines, restoring both functionality and visual appeal under the hood. Whether you're performing a complete engine rebuild, upgrading to an Edelbrock intake manifold, or simply refreshing aging hardware, this oil fill tube delivers OEM-quality fitment with a polished, show-ready appearance.

Constructed from durable steel with a protective chrome plating, the GM Style Oil Fill Tube withstands heat cycling, oil vapor exposure, and engine bay vibration without degradation. The tube provides secure oil access while the included cap seals the system, preventing pressure buildup and containment loss during operation. Edelbrock engineered this assembly to integrate seamlessly with GM intake manifolds, maintaining proper breather clearance and routing that ensures stable crankcase ventilation—critical for engine longevity and performance consistency.

Mechanics and enthusiasts tackling Chevy engine swaps, carburetor conversions, or manifold upgrades will find this kit indispensable for completing a professional installation. Compact dimensions (3.4 x 3.4 x 8.8 inches) ensure clearance in tight engine compartments while the lightweight design (0.69 lbs) simplifies handling during assembly. Installation requires only standard hand tools and basic mechanical knowledge; the tube threads into the manifold and accepts the cap without modification, making this a straightforward upgrade for both show builds and street applications.
