Hi guys,
My English Mk1 Morris Cooper S (Sept '66) looks like it has never had the two fuel tanks vent pipe clips welded to the underside of the rear parcel tray, but the are on the right side of the rear bulkhead. Has anyone got an S of a similar age that can say whether or not their car has them? An Austin here of a similar age has them but that is the only other car of the same age I've sighted. I was wondering if it might depend on where the body was Cooperized.

Regards
Al

Graham in Aus has an english S - '64 I think.... he'd be one of the few in Aus that would be able to help you, as ours were all built here

maybe ask on a UK forum as well?

Hi Simon,
Thanks for your help but I think I need to find a '66 which should have a factory right side tank. I'd be interested to know what Aussie assembled cars had but I am aware that there are a number of English assembled cars in Oz.

Regards
Al

I do not know how much help this is to you, But I have seen a number of genuine 1966 Cooper S with the tags on the rear boot wall and not on the top panel After 1966 I have never seen a genuine S without these tags

Yes, mine is a 64, so originally no R/H tank from factory, but mine was fitted with a 1960's 'Serck' aftermarket r/h tank a long time ago!

I figure it's a nice period accessory and part of the history of the car!

I do know however that early Aussie Mk1 S's also did not have the clips (as John has said) I have one of those too! It has a row of holes down the rear parcel shelf for some kind of clip to fit?

Anyone know what the clips looked like or were made of? Plastic?

Sir Alec! we are not worthy!

I have not seen a new clip for a very long time, The part number for the clip on seat brace 17H9524 ( Qty 2 ) for rear parcel shelf HYA1308 ( Qty 3 ) Drawing of the 17H9524 is on Page D-4 Mini Parts Book Pub1056M 1965 Model Cooper S used Clips not Tags

Bit more info to confuse.
Checked my parts book, HYL3262 Feb 65 page D-3 and it shows the clip as per the above post. In addition, since this is a Feb 65 parts book before the OZ built S was released, it shows the RH tank as an optional extra.
But the important bit is that the picture shows the tank breather tube going down to the boot floor on the same side as the tank with 2 clips required per vehicle, not across under the parcel shelf to the opposite side as on OZ built cars. So perhaps this may be more relevant for a UK built S.
Hope this helps.

I had alook at the parts book John quoted and the description for part No HYA1308 is "Clip-vent pipe to reat shelf - wiring"
Does anyone know what wiring means ?. Might help identify it as there is no drawing of it in the parts book

The parts book sure shows the vent pipe as Ron describes but the list of parts on the opposite page lists No 13 as the 2 clips on the seat brace and 3 clips No 13A for the parcel shelf.
Does thatmean that early Aus production cars had clips, not welded as John S indicates

My parts book calls the clip: Clip-Vent pipe to seat brace. (The seat brace is the seat back/bulkhead)
There is no 13A in my parts book.
IIRC parts with a HYA prefix are Australian designated part Nos and my book is before the OZ S was sold so it may well be a wiring clip of some sort but I don't recall any wiring going across under the rear parcel shelf on OZ built S cars, only the 2 tank vent pipes crossing over to opposite sides.

HY Part numbers does not always mean it is an Australian only part number eg HYL3662 is the part Number shown in the publication I mentioned before This is a Rubber uni joint, fitted to Australian & Uki Minis, They sometimes changed the part Numbers when the part was sourced In Australia These part Numbers Then Contained a Y
Another Point To Remember is that the wording & diagrams in these books are not always accurate ( see Diagram for Mini Door in same publication ( Is That not a Morris 1100 door ) then check page R-5 PUB1056 Part Number HYA1308 The Word wiring has disappeared.
It Is My Understanding That The Right hand tank was an optional extra on the Cooper S When First Sold In the UK

Hi guys and thanks for replying. There are a few interesting facts starting to show up now and a picture may be emerging. BTW, the welded type tabs/clips appear to be the same as the tail light wiring ones across the rear boot floor, possibly why they were referred to as wiring clips.

Also, apparently the English parts book notes a change in quantity of vent hose in '66. This suggests that in '66 each tank vented to it's own side, not crossed over like the earlier cars. Could I ask someone with the appropriate parts book to check that detail. If this is so, it may explain why the clips/tabs are not fitted to my car.

Hello John,
It's always puzzled me how BMC allocated part number prefixes and I haven't been able to find any info at all about this.
Is there any logic or system to it or is it just random? eg: some engine parts have an AEG prefix and others have say 12A. Why do some parts use 17H and others 21A and so on. Later Jaguar Rover prefixes seem to have DAM for many parts. There just doesn't seem to be any obvious system but I think there must be some logic in there somewhere.
Do you have any info about this?

Hi Ron,
I've been in the motor industry all my working life and I can't understand the BMC system either. The most basic item, hardware, doesn't follow any system and that is quite unusual. Beyond that, most manufacturers have a standard hardware/ description cross reference but not BMC!

Al,
From what little I know about it when, Austin and Morris were combined to become Nuffield back in the early fifties there was a lot of rationalisation of parts. Somewhere recently I found some info on the net that said there were over 30 different types of fasteners for the same thread size due to variations in head type, threaded length, type of washers, nuts etc and there was a lot of rationalisation around this time to reduce the number of different types.
This may have something to do with the part numbering system or rather the lack of an obvious system.
Who knows but it would be interesting to try and sort it out.
Well some of us find great delight in finding out about this sort of trivia. Well maybe it's just me.

RonR
