    Icon5 1976 16TS - Where to connect the hoses from/to the 'fuel vapour cannister'?

    I am now finalising the engine swap in my TS and having trouble finding where to connect one of the rubber hoses. I took some photos before removing the old engine but obviously not enough.

    On the LHS side of the transmission is a round black plastic canister with 2 hoses attached. I have found a place for the larger hose but not the smaller one. None of my manuals show this item as I gather it was only fitted to the later models.

    Any ideas would be welcome.

    Don

    Hi Don. I haven't had a '76 for a while now but from memory the thick black pipe goes from the charcoal canister to the carbie plastic cover and the smaller pipe attaches to a third steel fuel line. This third fuel line then runs with the other fuel lines beneath the car. The two petrol ones go to the tank while the third one goes to the expansion chamber inside your rear drivers side wheel arch.

    G'day Don,

    here is the relevant diagram for an r20, your setup should be similar.

    BTW, you'll find a bit of r16 data at Renault R-16 Parts Manual

    cheers,
    Bob

    There is no point. The only emissions the carbon canister controls are vapour from the fuel tank, even though the activated charcoal in the canister is now likely saturated, it does still perform a function with dealing with the vapour from the tank. It has no effect on the performance of the car itself, and is best left in place.

    As Sarosa has said, the small pipe will connect to the fuel lines going to and coming from the rear of the car, there will be one line from the tank to the fuel pump, another the fuel return line from the pump to the tank, and the third one from the carbon canister to the expansion tank at the rear.

    Thanks Sarosa. I traced the third line from the rear and sure enough it terminated hard against the bodyshell opposite the carby and out of sight to yours truly. So, the next job is to nut out which connections to the alternator go where. I assume that the largest terminal takes 2 connections.

    G'day Don,

    the vapour control system is one of the good guys, benefits the atmosphere and your car.....

    This oldie has a few words to say about emissions control https://dl.dropboxusercontent.com/u/...%20secrets.pdf

    Hi Bob,

    Thanks for the old information. It will certainly come in useful for my 20TS.

    Thanks

    David
