Default Vacuum Hose layout - CU Type 4 Engine

Hi there.

Does anyone have any photos or diagrams for what a dual carb and vacuum advance dizzy hose layout should look like on a 2-litre type 4 engine?

I'm removing a 009 and reinstating a vacuum advance dizzy anyhow, plus I'm not sure if all the right hoses are there even without the nwe dizzy. I can't seem to find one good authoritative source to go from so hoping someone here may be able to help.

Cheers

There's a port on the N/S carb. 3 and 4 cylinder side, use this port to connect the distributor to a vac source

Hi, thanks for the Ratwell link. I've seen that already, but found that also slighly confusing, as it's a different version of the 2 litre, doesnt have the air filter on (mine is much more boxey) and, I think, also an American vehicle so has more complexity.

Also, it reminds me, should I have a charcoal canister on my vehicle. I never have but the Ratwell articles made me think I should, but there is no reference in any manual or haynes etc!

If you’re fitting a SVDA distributor you won’t use the vacuum retard connection but if you have a brake servo the other lines will be the same, or similar to your engine. The air filter is a different shape but it has the same connections. You won’t have a charcoal canister.
