If you find out where the original tank vent line plumbed into the 1j inlet and make sure its in the same spot i hardly see you should have a problem. But dont charcoal canisters have a one way valve in them anyways?

Thx for the replies.
When your charcoal cannister is connected how does the tank vent when your engine isnt running like on a hot day?

Just bumping this back up.
Does anyone know if the size of the charcoal cannister matters?

the only reason your putting one there is to make an engineer happy, so as him.
alot of bikes dont run charcoal canisters, I've only ever seen a few that do.

Ok so we found out that they dont run 1 way valves in charcoal canisters, but if you vent it to the original factory position you shouldnt have a problem, i never ran 1 on my celica, and only till i enginnerd it did i have to put one on, and my honda also just vents to the atmosphere. So if you aint enginnering it dont be to concerned.

I've had a problem now and then where fuel comes out the line that goes to the charcoal canister. I assume its not a good idea to block the line up. Anyone else have this issue?

Yeah it is getting engineered.
Anyone with a 1J can you tell me which point off the inlet manifold the charcoal cannister goes to incase there is a non return valve fitted thanks. If its too much trouble ill have a blow and suck on my engine when i get home

Normally it runs off the 'E' nipple on the top of the throttle body.
I've never seen a one way valve there, but I've never worked on a car with a factory fitted turbo, its always been a conversion.
re: charcoal canister. Go find a wrecked MX73 Cressida. The charcoal canister is next to the exhaust manifold, under the brake booster.
I mounted mine here, coz I wanted it out of the engine bay (plus, there is no where to put it)

Just run a vacuum line to the back of the car, and mount it on the opposite side to the exhaust.

most EFI cannisets have the 1-way valve built in - most also havea solenoid between cannister and manifold to prevent any purging to the engine/atmosphere while engine is off.
if you can't find a suitable solenoid, then use a coolant-temp-controlled vacuum valve (found on any car with old-style emissions gear) to control vapour to the engine.
the solenoid might be optional but can leave you with an engien bay that always smells of fuel vapours and an engien predisposed to backfires when starting cold.
replicate a system like this:

and you should be fine and legal.

Interesting about the solanoid.
I don't run one with mine.
And I'm pretty sure the factory 5mge didnt either, but its not something I've looked into.

5M-E's run a Temp controlled VSV....pretty sure 5mge's would too?
1JZ's run an ECU controlled VSV as far as I'm aware? (the valve that hangs under the inlet manifold?).

Nah man, I'm pretty sure it was straight from the TB to the charcoal canister.
But I can't remember.

Do you reckon the engineer will pass it off without the vsv?
How did you go CrUZida?

He was fine with it all, I just had to secure it with something better than zipties.

I'm talking about your current super fandangled bracketry. He hasn't seen that yet.

Guys I got the following Rochester or AC Delco canister from a VP commodore yesterday:
I am confused how to hook it up. There are 4 outlets a,b,c and d which is located pointing downwards on the bottom face of the canister.
"C" is labelled "Fuel Tank" so no worries there.
"D" on the bottom I believe vents to the atmosphere.
"B" is labelled PCV, I have no way of hooking this up to my PCV so I just think it requires inlet manifold pressure.
"A" is not labelled but I think it controls purge or something and lso needs vacuum signal.
"C" and "D" have a direct path i.e. if I blow or suck in either air will go in or out of the other end.
If i block my finger on "C" and blow in "D" air comes out of "B" but will not go back the other way.
"A" obviously is a vaccum diaphram that controls the opening and closing of "B". If I blow or suck in "A" I hear the diaphragm working.
Any help?

Just going by this, hook up both A and B to the place on the throttle body.

Most of the others only use 3 nipples: tank, atmo and vac.

Yes, but this one has a vacuum switch on it that needs to be operated inorder for the CC to do its job.
Hence both A and B need to have constant vacuum.

Thanks for the replies.
Im raking my brain, but unfortunatley I dont seem to know anyone with a commodore which I could take a squiz at, I think it's pretty self explantory though. Do you think I should still be fitting a non return valve in the vacuum signal lines for when it's on boost, or perhaps the diaphragm on the canister might perform this function?
I think I need to hook a hose to each port and start teh blowing and sucking

Most definately put a oneway valve in.
You dont want something to go wrong and pressurise the fuel tank do you?
