MotoRad Fuel Tank Cap for Mercedes‑Benz Sprinter 1500/2500/3500 (2015–2023) — MGC934T, OE-fit with pressure/vacuum relief

MotoRad MGC934T is a direct-fit replacement fuel tank cap engineered to restore proper pressure and vacuum control on Mercedes‑Benz Sprinter 1500/2500/3500 models from 2015 through 2023.

If your Sprinter’s factory cap is worn, cracked, or no longer seals tightly, the MGC934T restores the vapor control and sealing performance required to meet state and federal emissions rules. Built by an OE supplier to align with original specifications, this cap combines durable materials with pressure and vacuum relief features so the fuel system maintains correct tank pressure and evaporation control.

How does this cap help prevent fuel evaporation?

The MGC934T includes calibrated pressure and vacuum relief valves similar to OEM units, which limit uncontrolled vapors escaping from the tank. A secure seal and functional vents keep fuel vapors contained until the vehicle’s purge system routes them to the engine.

• Precision relief valves reduce evaporative emissions.
• Tight sealing gasket minimizes fuel seepage and odor.
• Durable metal construction resists cracking and wear.

Will this fit my Mercedes‑Benz Sprinter model year?

The MGC934T is designed for Sprinter 2500 (2015–2023), Sprinter 3500 (2015–2018), and Sprinter 1500 (2023). Always confirm fitment for your exact model and fuel system before purchase to ensure compatibility.

• Compatible with specified Sprinter model years listed on the product page.
• Check your vehicle’s OEM part number or use a fitment tool for verification.
• Compact 4 × 4 × 4 inch dimensions for straightforward replacement.

What materials and safety standards does this cap meet?

Manufactured by MotoRad through an OE supplier, the cap is made from aluminum or stainless steel components selected for corrosion resistance and long service life. It’s produced to meet state and federal emissions requirements and common industry safety standards for fuel system components.

• Aluminum or stainless steel for corrosion resistance.
• OEM-quality manufacturing process and safety checks.
• Meets emissions requirements to help pass inspections.

How easy is installation and what practical benefits will I notice?

Installation is a simple, tool-free swap in most cases—unscrew the old cap and thread the MGC934T into place until it seals. After replacement you should see reduced fuel odor at the filler, fewer evaporative vapor leaks, and restored confidence in your fuel system integrity.

• Simple hand-tight install on the filler neck; no special tools needed.
• Improved sealing reduces fuel smell and vapor loss.
• Helps avoid false EVAP system errors due to a failed cap.

Who is this for: The MotoRad MGC934T is ideal for Sprinter owners, fleet managers, and independent mechanics who need an economical OEM-quality replacement fuel cap that meets emissions standards and restores proper tank pressure control. It’s especially useful for vehicles showing fuel odor, EVAP warnings, or for preventive maintenance on older caps that show wear or damage.
