Tomei 740cc injector:

hi. can anyone tell me how to change the injector on a sr? and do i need any new parts when i install? thanks!

you pull out the old ones, put in new o-rings and put in the new ones.

where can i get the new o-ring? how mcuh is it? thanks!

Nissan, probably a few bucks each.

OK thanks. But how i have to do when i change the injector. Do i need to disconnect the fuel before i take the injector out? Because i think there is a fuel inside. thanks!

Pull out the fuel pump fuse. Start the car and let it die … that will release line pressure and drain the fuel.

Uhm, I’m assuming you have something to control the extra fuel?

yes i do. i have a e-manage with injector harness. i think it should be ok. :lol: thanks alot.
