anyone with a 3b got a photo of where these lines go and what is the black one way valve which runs on a hardline round the back of the battery then dips into the wing.

definately got the one to the TBV sorted, its the other two i'm not so sure about.

The FPR va line has a T in it but not sure if that one goes to the back of the IM and then the other end of the T down the the small guage semi rigid vac pip coming up from under the batter tray or not. anyone confirm?

Cheers

Ac equipped cars have a 1way valve so that it keeps the front vacuum reservoir empty - used only for function of recirc flap. There is another pipe that goes to rear of car via another 1way into vac reservoir for dufflock

On ABY the hoses are Color coded - red plastic to the rear, think it is black to the front with a green one to the ecu via the obligatory moisture trap. Hey - I can show you over the weekend !!!!!!

yeah thats true...i mean the car is running so its only a minor niggle but just want to be sure they are plumed in the 'correct' way Yep the car doeshave a/c, who knows it might even work again tomorrow so that might explain the additional one way and hardline.

The black line that goes round the back of the battery and dips into the wing goes to the front vac res.

ah ok - thanks for the clarification John. sooo, which lines are connecting to that valve and is it a single/direct connection off the IM connection or a T'd one.

David, the vacuum hose that runs down the side of the battery tray and disappears inside the car is the ECU vacuum hose. I had mine connected by a length of vacuum hose running from the middle outlet off the IM with a 'T' piece which was connected to the FPR and the rigid ECU hose. The ECU is actually green but it can be very difficult to see as they get so dirty with age.

There are some dark green rigid hoses that run around the back of the battery and into the wing but I'm fairly certain these were linked to the carbon canister?

[newsh]

lol just edited due to confusion I've removed my carbon can now so exactly sure. There should be a little black and yellow valve with a T off it to do the larger pipe, and a small T in the FPR line I think, sorry , not really helping.

[s2driveruk]

from memory there is another semi rigid line which comes up fromabove the steering rack - any ideas what that one was supposed to suppy?
