Locking fuel cap for Ford Mustang 2015-2023 & Escape 2017-2019

Overview

For certain model years of the Mustang and Escape, Ford switched to a capless fuel system—no classic screw cap, but a flap with sealing lips that simply opens when refueling. Convenient at the pump, but without a lock, anyone with a funnel or hose can access your tank. The Locking Fuel Plug closes exactly this gap: it is inserted into the existing fuel opening and can only be removed with the corresponding key.

The part is black, features embossed "Lock" and "Unlock" logos, and only works if your fuel opening has the two notches required for the plug to seat securely—more on that below.

Important: The plug only fits if your fuel opening has the two notches for the locking mechanism. Not every capless version comes with these as standard—check your opening before you order, or send us your VIN and we will check it for you before any money changes hands.

Installation & Notes

Installation requires no tools: insert the plug into the fuel opening until it clicks, lock it with the key—done. To refuel, simply unlock it, pull the plug out, refuel as usual, replace the plug, and lock it again.

A few practical points that we are often asked about regarding this part: Model year and trim level can vary greatly for the Mustang and Escape—not every model year necessarily has the matching notch receptacle in the fuel opening, even if the vehicle is generally on the fitment list. According to the manufacturer, the four mentioned OEM numbers are in circulation across several model years and trims—the most reliable way to determine which one is actually installed in your car is to take a look at your vehicle or perform a VIN check. We import from the USA and check parts personally before they are sent to you—if you are unsure whether your Escape or Mustang has the correct capless system with notches, send us your VIN, and we will tell you if it fits before you buy.

FAQ

Does the Locking Fuel Plug fit every Mustang or Escape?

Only if the fuel opening has the two notches for the locking mechanism and your model year is on the fitment list (Mustang 2015-2023, Escape 2017-2019). When in doubt, send us your VIN and we will check before purchase.

Is this part new or a used part from a US vehicle?

It depends on the specific offer—we source both new parts and tested used parts from the USA. Ask us directly what is available for your car.

How long does delivery take if the part comes from the USA?

This is an import—expect significantly more than a week, depending on availability and customs. We will provide an exact date once we have found and inspected the part for you.

Can I return the part if it doesn't fit?

As a consumer, you have the statutory right of withdrawal—the details are in our cancellation policy. Even easier: contact us before buying with your VIN, and we will clarify the fit beforehand so you won't need to return it at all.

Do I need tools for the installation?

No. Insert the plug into the opening, let it click into place, lock with the key—that's it.
