Gas Cap, for Beetle 68-71, Bus 72-73, Ghia 68-71

OVERVIEW

When it comes to maintaining the integrity of your classic air-cooled Volkswagen, the fuel system is often where the most critical details are overlooked. This EMPI stock replacement gas cap is engineered to provide a factory-spec seal for your 1968 through 1971 Beetle and Karmann Ghia, as well as the 1972 to 1973 Type 2 Bus. Many enthusiasts don''t realize that a worn-out or ill-fitting gas cap is the primary culprit behind that persistent "gasoline smell" inside the cabin or garage. This high-quality replacement features the correct 65mm neck fitment, ensuring that fuel vapors stay contained and atmospheric pressure is correctly regulated within the tank. Whether you are finishing a ground-up restoration or simply replacing a cap that has lost its tension over the decades, this unit provides the peace of mind that only a fresh, tight-sealing component can offer.

It is a common misconception among VW owners that purchasing a brand-new fuel tank includes the cap; however, most replacement tanks are shipped bare. This EMPI 113-201-551A cap is the industry standard for bridging that gap. Manufactured with durable materials designed to withstand modern ethanol-blended fuels, it resists the corrosion and seal degradation that often plagues original 50-year-old parts. The internal venting mechanism is calibrated to function seamlessly with your vintage Volkswagen''s fuel delivery system, preventing the vacuum lock issues that can leave you stranded on the side of the road. Don''t let a five-dollar part ruin your driving experienceupgrade to a fresh seal and ensure your fuel system is operating at peak efficiency and safety.

PRO TIPS

Tip 1: Inspect Your Tank Neck Surface

Before installing your new gas cap, take a moment to inspect the mating surface of your fuel tank''s filler neck. Over time, these necks can develop rust pits or small dents from gas station nozzles. Even the best EMPI gas cap cannot create a vapor-tight seal if the metal surface it presses against is uneven. If you find rust, use a fine-grit emery cloth to lightly sand the rim of the neck until it is smooth and shiny. This ensures the rubber gasket on your new cap can compress evenly, preventing fuel leaks during hard cornering and stopping those annoying gas fumes from entering the cockpit.

Tip 2: Understand the Venting System

1968 and later Volkswagens utilize a more complex venting system than the earlier "pea-shooter" style tanks. If you install this cap and notice your engine starts to stumble or die after 20 minutes of driving, you might have a blockage in your vehicle''s expansion tank or charcoal canister lines. This cap is designed to work with the factory venting loop. If your vent lines are plugged, the fuel pump will create a vacuum in the tank that the cap cannot overcome, leading to vapor lock. Always ensure your vent hoses (located behind the spare tire in Beetles) are clear and not cracked or collapsed.

Tip 3: Gasket Maintenance for Longevity

Modern gasoline contains ethanol, which can be much harsher on rubber components than the fuel available when your VW was new. To extend the life of your gas cap gasket, we recommend applying a very thin film of silicone-based grease or "Brake System Silicone" to the rubber seal once a year. This prevents the rubber from sticking to the filler neck and tearing when you remove the cap at the pump. It also helps maintain the elasticity of the seal, ensuring that it remains pliable enough to conform to the tank neck for a perfect, airtight fit every time you fuel up.
