Fuel Tank Sending Unit Gasket 1J0919133A URO Parts OE‑Fit Round Seal

Description

Product Overview

The URO Parts Fuel Tank Sending Unit Gasket, model 1J0919133A, is engineered to meet the exacting standards of original equipment manufacturers for high‑performance European automobiles. Crafted from a high‑quality, machined rubber compound, the gasket delivers a consistent durometer that matches the OE specification, ensuring a long‑lasting seal that resists degradation from fuel exposure, temperature fluctuations, and vibration. Its round geometry, measuring 124.5 mm in outer diameter and 21 mm in width, aligns precisely with the top flange of fuel pumps that have a 123 mm O.D. opening, creating a seamless interface between the fuel tank and the sending unit.

Beyond its dimensional accuracy, the gasket incorporates a proprietary sealing technology that distributes pressure evenly across the contact surface. This design eliminates micro‑gaps that could otherwise allow fuel vapors to escape, a critical factor for meeting stringent emission regulations. The gasket’s low‑compression set ensures that even after repeated removal and reinstallation of the sending unit, the seal retains its integrity without the need for additional sealants or adhesives. Each unit is inspected for dimensional tolerance and surface finish before packaging, guaranteeing that every customer receives a component that performs as intended from the first installation.

URO Parts has a reputation for delivering components that combine durability with ease of installation. The gasket’s lightweight construction—just 1.6 ounces—means it adds negligible mass to the fuel system, while its robust material composition provides resistance to chemical attack from gasoline, ethanol blends, and common additives. The product dimensions of 5 × 5 × 0.75 inches allow for convenient handling and storage, and the machined exterior finish offers a smooth surface that reduces the risk of abrasion against adjacent metal parts during assembly.

Designed specifically for a subset of Audi, Porsche, and Volkswagen models, this gasket is not a universal part. Compatibility is determined by the vehicle’s VIN, and it is essential to verify fitment with a qualified dealer before purchase. When installed correctly, the gasket eliminates the common issue of fuel tank vapor leaks that can trigger emission test failures, providing peace of mind to owners who demand both performance and compliance.

Usage

The gasket is intended for use in vehicles equipped with fuel tanks that employ a sending unit with a top flange of 123 mm O.D. It is ideal for both original installation on new vehicles and as a replacement part during maintenance or repair procedures. Typical scenarios include fuel pump replacement, fuel tank removal for body work, or any service that requires the sending unit to be detached from the tank. In each case, the gasket should be inspected for damage and replaced to maintain the integrity of the fuel system.

Installation is straightforward for technicians familiar with fuel system components. After removing the old gasket, clean the mating surfaces of the tank and sending unit to remove any residual fuel, debris, or old sealant. Position the new URO Parts gasket so that the machined side faces the tank interior, aligning the central hole with the sending unit’s mounting points. Apply even pressure to seat the gasket fully, then reinstall the sending unit according to the vehicle manufacturer’s torque specifications. The gasket’s design ensures that it remains in place without shifting, even under the dynamic loads experienced during normal driving conditions.

For DIY enthusiasts, the gasket offers a reliable solution that does not require specialized tools beyond standard torque wrenches and basic hand tools. However, because fuel system work involves handling volatile liquids, safety precautions such as disconnecting the battery, relieving fuel pressure, and working in a well‑ventilated area are strongly recommended. When these guidelines are followed, the gasket provides a durable, leak‑free seal that supports the vehicle’s fuel delivery and emission control systems for the life of the component.
