I bought the carbon canister second hand off the internet so I do not have a clue where it goes and I have not seen one fitted to a real vehicle. Apparently I have attached a photograph which I have drawn arrows and text boxes in.

It does not look like it from the photo but the vapour filter clips on as a snug fit at the bottom of the carbon canister.

Kind Regards
Lionel

HI Lionel, That just goes through a hole in the inner guard and vents to the road. The fuel tank uses a non venting cap so I imagine that in really hot weather and when people insist on trying to get every last drop in the tank it would be possible to get some fuel to push up the vapour lines ( there is a fuel/vapour separator inline near the tank but it is small). I think that this would be to let fuel drain out of the canister as opposed to vapours which are supposed to be held in the charcoal and drawn into the carby when the engine is running to be burned.

I'll get a pic on Saturday. The lines are marked on mine so you should be able to hook the top ones ok. One of the lines comes from the fuel tank, one from the top of the carb and the one marked 'purge' is connected to the bottom of the carb so it is probably using vacuum to restrict how much vapour is returned to the carb at idle.

G'day Bernie,

Thank you for the offer of photographs and also solving the issue of where the bottom pipe goes off vapour filter. One less mystery.

I am going to be putting a carburettor a step back in time from the HX-HZ which my engine is. I am going to go a complete HJ system. This involves just a line from the tappet cover to the air cleaner; a pipe off the side of the carburettor leading to the carbon canister; a line from the fuel tank to the middle coupling of the canister. Lastly, a pipe from the right side of the canister with a tee off the inlet manifold which then leads to the back of the tappet cover near the firewall that has the PCV valve fitted.

It will be a complete anti pollution system - not the elaborate and from what I have heard is a restrictive system that the HZ had.

It is all going in Land Rover Series III so I am hoping that there may be some lenience during an inspection of a mechanic not knowing what should be fitted where between a Holden and a Land Rover back in the mid 70s. In 1976 period when my Land Rover was made and 1977 when the Holden engine was made - fingers crossed it gets through the rego inspection - when it comes time for it. Got to get it to make vroom vroom noises first!

Kind Regards
Lionel

Some pics for you.

Attachment 124141Attachment 124142Attachment 124143Attachment 124144Attachment 124145Attachment 124146Attachment 124147

1 – the canister sits on the inner guard just behind the drivers side headlight
2 – the markings on the cannister
3 – the hose from the 'carb' point of the canister to the top of the carb
4 – vent in the top of the rocker cover, this attaches to the air cleaner housing
5 – pcv valve
6 – hose from the pcv valve to the bottom of the inlet manifold
7 – hose from the 'purge' point of the canister to the bottom of the carby

Cheers

Hello Bernie,

Thank you for all the photographs. It certainly makes things clearer. Is there any chance of getting a photograph of the air cleaner and pipes being in their proper place as if the engine was ready to start?

This is the one of two photographs or diagram that no one in auto manuals seem to include. The second omission is a photograph that shows where the pipe off the accu-themo AC disk shape on the top of the aircleaner trumpet connects to. Does the pipe I have arrowed go from the circle accu-thermo AC to the fitting on the base of the air cleaner that is positioned just near the air cleaner filter? There are two pipe connections off this part where does the second pipe go as this part has two pipe connections on it.

There is also a mounting for a corrugated foil-like pipe that fits over the circled area in the second photograph. Can you please let me know what this corrugated foil-like pipe actually goes to an connects to? I borrowed the photographs Accessed June 4, 2017 from, Holden Factory Air Cleaner | eBay. The last two photographs are taken from my ailing camera - sorry about the picture quality. The photograph shows the switch that sits near the air cleaner filter and the last photographs shows the bottom of the air cleaner base and is meant to show that there are two pipe connections that fit to the "AC" switch.


Sorry about all the questions. - Bernie

Kind Regards
Lionel

The soap opera which is me putting through a kit on the Stromberg on Darwin has reached a crisis while I rest up waiting on the Royal Hobart finding some space for me.
Does anyone know what these two items are / are for etc - I cannot see anything like it in the carby I am stripping down and I cannot see anything like it on the rather poor diagram supplied with the kit.
Any comments gratefully accepted as usual.
cheers,
D

Oh - found it in the scribd document it is - q. X2 plastic caps for blocking off vacuum lines (not used in the overhaul of bxov-1 carbs.
Cheers,
D

Hi Lionel, sorry I dont have a foil tube any more, it might have been to something on the exhaust, mine has headers. I am gradually buying the HQ service manuals as I spot them cheap on the bay or swap meets but I dont have the HZ supplement so I havent got anything to look it up.Too many projects so the HZ hasnt had any loving since I stopped daily driving it [bigsad]

Spent an interesting hour or so attempting to work out how you attach the pump link spring clip , could I find anything on the net to show me ?! Nope.

So attempt no. 1 not happy - attempt no. 2 happier but would appreciate a heads up on whether either is correct or should it be done differently.

Secondly , the pump stem spring doesn't close the throttle valve completely. I am assuming (never assume!) this is how it should be as apart from making the spring stronger I cant see how you could adjust this , but would also appreciate another heads up on this one.
All comments gratefully received as always.
cheers,
D

p.s - I think I'm missing the return spring!

Attempt 1 wrong...
Attempt 2 correct...gold star[emoji12]

Cheers Rod

A bit like a jigsaw puzzle - the more i managed to fit on , the more it made sense. All good to go barring some pipework and possibly some kind of spacer as from memory i think the throttle cable bracket fouled the manifold. Hoping im wrong - its so long since i took it off!
cheers,
D
