Thanks for that. I've tried to look up inside the filter with a mirror but couldn't see a Hex socket. Not that i have a 14mm Allen key anyway and if I did it would have to be at least 7" long to reach. Obviously I don't want to damage it in trying to pull it out if it is threaded.
I would say that it will be exactly the same & unscrew.... They are really Flippin tight mind as mentioned & you will more than likely want an allen socket & a breaking bar to crack it... Dean
I used a long allen socket as below to allow plenty of purge with precise control. Stahlwille STW205414 | Stahlwille Trade Prices | STW205414 You should be able to get one from a good motor factors or FleaBay Cheers Dean
