Fuel Tank Cap Overview

The Motorad MGC519T is a push vent tethered fuel tank cap built with OEM-quality materials and safety standards. It is engineered to maintain proper pressure and vacuum control while helping reduce fuel evaporation on a wide range of applications, including Chevrolet Express, GMC Savana, and Ford Super Duty models.

Key Features

• Push vent tethered design for the specified fuel system application
• Pressure and vacuum relief valves help control tank venting
• Plastic construction with a green finish
• Non-locking cap design
• OE supplier manufacturing approach with emissions-focused compliance
• Part number MGC519T for easy identification

Detailed Description

This fuel tank cap is designed around the listed neck diameter of 1.750 inches, with a shell diameter of 2.813 inches and a cap depth of 2.125 inches. The pre-vent, pressure-vacuum venting setup supports proper fuel system sealing and helps limit evaporative loss, which is important for emissions compliance and consistent tank operation. The Motorad MGC519T is a direct replacement style cap for many Chevrolet, GMC, Ford, Nissan, Dodge, Toyota, Jeep, and other applications shown in the fitment data. This part cross-references Monroe Shocks & Struts (e.g., 9MGC519T, 10819T) for the same application.

Compatible With Chevrolet Express 2500, Chevrolet Express 3500, Chevrolet Silverado 2500 HD, Chevrolet Silverado 3500 HD, GMC Savana 2500, GMC Savana 3500, Ford F-250 Super Duty, Ford F-350 Super Duty, and many additional listed applications. The MGC519T is also a relevant replacement for Chevrolet C/K trucks, GMC C/K trucks, and several van and SUV platforms where the push vent tethered configuration is specified.

What It Helps Address

• Fuel vapor loss from a worn or leaking cap
• Check engine concerns related to evaporative emissions sealing
• Improper tank pressure or vacuum control
• Cap fit issues caused by damaged sealing surfaces
• Loss of tethered cap retention on the fuel filler neck

Installation Notes and Tips

Verify the neck diameter and venting style against the original cap before installation. Confirm the application notes in the fitment list, since this cap is specified for push vent tethered systems and not every vehicle in the same model family uses the same fuel cap design. The part number MGC519T should be matched to the original cap or service information for the vehicle.

Quality Assurance

Motorad states that this cap is manufactured to OEM quality standards by an OE supplier and is built to meet state and federal emissions requirements. Its pressure and vacuum relief design is intended to help prevent fuel evaporation and support proper evaporative emissions sealing.
