2 lugs have broken on my water filler cap, I got a replacement off eBay without a locking barrel as I wanted to switch my existing one in. Now I’ve found the internals are different. The old one has 2 large recesses and the new one 4 smaller recesses. So the bit you press in on the lock barrel is too wide, so it doesn’t fit. The eBay supplier says this is all they have. I thought I had a Zadi barrel, but maybe not. Does anyone know what cap I need. I don’t want an extra key. Ta very much.

Thanks Janine but I can use the new non locking cap for the time being as it fits perfectly well in the hole, it’s just the lock bit that’s the problem.

Does it need to be locked, ours never is.

There are different barrel fittings. I contacted Brownhills (they have a store on eBay) and they helped me get the right one.

Mine was this one eBay (not Zadi) but yours could be different depending on the year.

Can you not swap the bit with the lugs on?
Thanks. The lugs are broken on the original cap. I’m trying to get the old lock into the new cap with lugs.

No it doesn’t have to be, it’s just a bit of security against someone nicking it or worse putting something unpleasant into the water.

Thanks very much for that. I maybe should have said it’s for a Hymer, I’ll see if this is the same. Of course it’s twice the price of the eBay one.

I changed mine to a different key locking one after pulling up at a garage and just as I was about to pull the diesel trigger noticed I’d put the nozzle in the water inlet!!! (One key unlocked all external locks !) I’ll hopefully never make that mistake again 🫣
