Flip Top Fuel Filler Neck & Cap, for 2 Inch Inlet

EMPI Flip Top Fuel Filler Neck & Cap for 2-Inch Inlets

Volkswagen Fitment & Application

The EMPI Flip Top Fuel Filler Neck (Part #6034) is a universal component designed for high-performance and custom VW applications. It is specifically engineered to fit any 2-inch diameter inlet. This assembly is a favorite for custom builds including Dune Buggies, Sand Rails, and Baja Bugs where quick access and security are paramount. The integrated mounting flange allows for a secure installation on custom fuel tanks or body panels, making it an essential upgrade for off-road enthusiasts who want to eliminate the risk of losing a traditional twist-off gas cap.

Pro Tech Tips from Appletree Auto

Optimize Your Seal: When installing the mounting flange, always use a fuel-resistant gasket or a high-quality fuel-safe sealant between the flange and the mounting surface. This ensures that even in rough terrain, fuel vapors stay in the tank and moisture stays out, protecting your engine from contamination.

Maintain the Quick-Action Latch: To keep the spring-loaded mechanism operating smoothly, occasionally apply a small amount of dry graphite lubricant to the hinge and latch points. Avoid using heavy greases that can attract desert sand or grit, which could cause the mechanism to bind or wear prematurely.

Confirm Venting Requirements: While this cap is designed to be vented, always verify that your fuel system's overall venting strategy matches your engine's fuel delivery needs. In high-performance applications, ensure the vent path remains unobstructed to prevent vacuum lock, which can lead to fuel starvation during wide-open throttle runs.
