W460 locking fuel cap with vent for W460's (230G, 230GE, 280GE, 240GD, 300GD).

Recently we have had some issues with fuel caps not fitting the trucks. This in some instances happens with trucks that are imported and restored and also previous military trucks. The companies bring the trucks in are modifying the fuel filler neck to take a different (usually smaller and cheaper) cap.

Original Mercedes-Benz part.
