It’s actually brass and came out quite well with an easy out .
The plug looks the proper job so obviously nothing to do with BMC :lol: :lol:
That’s a genuine plug , can’t remember the part number, got a bag of them somewhere.
21A352!

To summarise some of this discussion, the initial drain plug part 21A352 (as per Beatie's post) was replaced by the plug with tube - part 21A1401.

BMC Australia made its own equivalent of 21A1401 giving it part number AYA2150 for the threaded bit and AYA2149 for the assembly.

If ever there was an advert for the usefulness and the depth of knowledge available here, just see the post above.

Brilliant!

Really useful info, and just found this in the site's BMC bulletin - with dates ;-)

Ok, Not a solution for the 10/10 conservator, but a great solution if you ever want to remove the tank again.
Right, finally got to the stage where I can fit the tank and the boot floor has the hole in the wrong place. Ho hum (M-Machine Mk1 Spec floor). What glue would folks recommend for this task? I've tried a calliper plug screw, that's too short to go all the way up to the taper and I suppose the nipple should be tight against that to seal it against leaks.

JB Weld followed by a 3/8 UNF grub screw. I have ones that have been like that for 30+ years & have never had any issues.

I’m not sure that’s quite correct. The drain tube with pipe is pictured in the original Mini Cooper parts list and is labelled as 21A352
Confusing!

I'm just getting to this issue at the moment, as mentioned by Andrew - it's there and would like to return same even though I can see they are a right pita. Dermott directed me to some for sale in Australia but their web site doesn't seem to be set up for selling abroad - pinged them an email but no response.

I'd like to know if the grommet is just a blank with a hole through or whether it is a thicker moulding that also acts as a supression rubber?

The slinger thingy however is still a hurtful point Andrew - my therapist has given up trying to get me through this :o :lol:

There’s a few places in Aus that sell them. If you want to order a few to make it worth the shipping and fees I’d be happy to receive them and post them on

I sent a small quantity of the NOS tubes to someone on here, but can't remember who.

I was me and yep, I think I still have a few (3 I think) as some who wanted them at the time didn't follow up once they'd arrived. Richard, pm me if you want any. The grommet I have was cleverly hand made by Dermot, but are now available at Somerford mini.

Andy I've been replying backwards to the posts and have said yes to Timmy - Timmy if you don't mind :oops: it would make sense for effort/postage if I were to get these from Andy - but again thank you!

Sorry for causing your problems Richard and hopefully your therapist will sort out your issues :lol:

The grommet sits on the boot floor, covering the hole and protruding through, rather than fitting like a conventional grommet.

I made a socket like this to fit and nip up the drain as it's almost impossible to get to with a spanner. I'll find a pic and post up, but here's a pic of the socket I made. .. cut a deep 7/16 1/4 "drive socket in half and then weld a bit in the middle !!
