yaar how can u intall the pipe if u remove this nozzle.:S.
the kits now coming to pak hava'nt got these nozzles, as i found it when i got gli converted to cng before choti eid.
in corolla, gli the connection is given from the heating pipe going to the throtle body. i guess u have sunny and i again guess that it is not efi and if my guesses are true than u'll have to give the connection from the pipe going and coming from the heater readiator(the small heater radiator which is inside the heater main body).
though i did'nt noticed any performance or consumption gains after installing the ater circulation system.
