Doubt about the canister urgent

Hello my question is as follows: I have a Suzuki Swift of the old man g13 year 89, and I already bought it by 2nd hand, the problem is that it does not have the valvila Evap or gase recirculator and for this reason the maguera that leaves the canister towards admission is at the loose because the valve is not Manguerita where gasoline vapors come out, and I want to know if while I can get the valve it is possible to seal the hose, what consequences it has if the seal or something helps ...

Remember that the canister in some cars to be a gase recovery is also releasing of the cobunsible tank, if your car works with this system C can inflate the same if it cancels it, the last one puts a hose as a hose as the trace axis made the gases will not enter the cabin.
