Restoring my Austin Cooper S MKI 1965 (reshelled w/ Cooper MKI body, I suppose) I would like to bring it back to its original form. Having already installed twin tanks , now I wonder - as I cannot find information in my bibliography - what would be the correct routing of the 2 vent pipes and if they both go through the boot floor, like the pipe to gas pump and respective wiring ?

Also the SU pump has two 'vents' wondering what will be the correct routing of the vent pipe to be installed in that one closer to the membrane - (it seems that the 'vent' closer to the boot of the pump it's a pressure and vacuum 'valve'?)

If someone have pics it would be much appreciated!

Thanks.:)

The vent pipes run from side to side - the vent pipe for the left hand tank vents through the right hand side of the boot floor and vice versa.

I have a picture of how I did mine, like Simon has stated.

Here it is - please bear in mind my car is a replica and I've fitted the pipes how I understand them to go following research and checking with John Kelly, the Mk1 S guru. :)


There are some special clips to hold them up to the underside of the rear parcel shelf tray. The closest I have found (and used) are the brake servo pipe clips that John Kelly sells on eBay and I used the screws that hold the seat squab into place.

I could be wrong but I think this set up changed when the twin tanks became standard fitment in 66.

Why do you think it has been reshelled?, twin tanks were not standard in 65'

Thanks to all who have answered and helped to sort out petrol tanks pipes vent routing. Special thanks to John Kelly also!

Speccially to Andrew1967 for the picture! Conclusive no doubt! may I ask you for other pics showing other details? I would appreciate.

I suppose that the car has been reshelled as due to its documented race history and several details not according 1965 MKI spec sheet (glass dating codes, quarterlight windows not 'piano' type hinges but sprung claspes (August 1967), etc...). This car was CKD to Portugal in January 1965, having 'left' Abingdon in October 1964, and extensively raced in '65 and '66.

Thanks.

:)

see PM please.

One more question...

The SU pump I've used has two vents. One close to the membrane and another one in the 'boot' of the pump (this one seems to be one 'vacuum and pressure 'valve''). Question is , these vents should be connected to somewhere, if so where to?, or they should be kept 'open' (no pipe)?

Thanks

The one on the boot of the pump should have a little clip cap to hold in the ball bearing. The other usually has about a 6" piece of flexible tube pointing down.

The pipe from the body of the pump should go to a small plastic connector on the rear subframe.

Hmmm. Just had a look at the parts books, AKD3509 and AKD5104. The fuel pump for the MK I seems to have no vents. That for the MK II looks to have the two vents being talked about, one on the back and one by the pump membrane. I've tried to attach a photo of the back end of a MK II pump.
Cheers

So should there be anything attached to the end of this?

I did notice in my AKD3509 that no vents were showing but haven't got a Mk2 mechanical parts manual.

on my january 64 car the small vent has a small piece of plastic tubing and vents into the car just below the rear seat via a small plastic connector already fitted to the bodywork . I think JK mentioned this in the club mag some time last year, with all part numbers, will try and dig the article out, cheers Tim

i,ve just found the article in Nov 2004, and it states that the idea being that clean air was picked up from inside the car, rather than the pipe venting out under the car and getting gunged up with dirt. The part number of the 10inch long breather tube - 97H2679, and the nylon rivet to body- 13H1640.

Hmm, I do recall seeing that article from what you mention. I'll have to dig it out and have a read.

Once the snow has gone, I'll get the yellow peril up on some ramps and see about fitting said pipe! :D

Thanks for the posts Tim.

The left hand tanks are identical.

I suspect this one made more money than ususal as it's an early screw type sender tank with the sender still fitted.

Thanks again to all  for your complete explanations, I will try to put in pratice all the procedures and let you know with some pics here.

I've never 'used' the MCR Forum before (I'm MCR member since 2003, I suppose) to solve my naif questions,but I see this is the place where we should come and ask for help!

I have more questions, dont go away...

Thanks Andrew!

:)
