Replacement Fuel Filler cap
For the third time in my life I left my fuel filler cap on the forecourt of a European garage. I carry a push-fit replacement to act as a stop-gap, but does anyone know of a source for a replacement? From memory the cap is identical to a lockable water filler cap (and I think my last replacement came from such a source), but I worry that this is not a suitable replacement. Provided I can make the file upload thingy work, I attach a picture of the type of cap that was fitted (appearance-wise).
