Types Of Filler Caps
Screw-In Filler Neck
Description:
A screw-in filler neck has internal threads, so the fuel cap literally screws in and out to seal the tank.
Typical Features:
-
The cap rotates several times to tighten and seal.
-
You can feel the threading action as you twist it.
-
Common on European and older vehicles (some Mercedes, BMW, Land Rover, etc.).
-
Provides a very tight seal — ideal for pressurized or vented systems.
Fuel Angel Fitment:
If your cap screws in like a jar lid, you’ll need the screw-in version of the Fuel Angel.
Bayonet Filler Neck
Description:
A bayonet filler neck uses lugs or slots instead of threads.
You push in and twist about a quarter turn, and the cap locks in place with a satisfying click.
Typical Features:
-
Quick twist-lock design (¼ turn to open or close).
-
No visible threads inside the filler neck.
-
Common on modern vehicles and vans, including most Mercedes-Benz Sprinters, Ford Transits, and US market cars.
-
Designed for fast filling and easy access.
Fuel Angel Fitment:
If your fuel cap just pushes in, turns slightly, and clicks, you need the bayonet version of the Fuel Angel.
Quick Way to Check
-
Remove your fuel cap.
-
Look inside the filler neck:
-
Threads = Screw-in type
-
Two or three locking slots = Bayonet type
-
-
If unsure, snap a photo — the pattern of the opening usually makes it clear which version fits.

🔧 Protect Your Diesel Fleet from Misfuelling
