Injector install problem..

[mijake]

I have just bought some 555cc Nismo injectors for my r33 fron Greenline JP. The injectors are yellow.

Now i spent tonight pulling the plenum off which was a bit tricky but i have gotten to the stage where i have the fuel rail out and am staring at the injectors. I couldnt get them out so i have soaked them in crc to see if they are easier tomorrow morning to get off.

But what i noticed was that my new set of injectors didnt come with any of the o rings. Do i need to buy some new ones and where can i buy them from? Or am i supposed to use the old ones?

Help please

Thanks

Michael

it would be a good idea to use new ones, give you local efi shop a call, if not try some injector cleaning guys, either way it wont cost you much

Buy a set of o rings that were meant for the std injectors. Using std rail + straight drop in injectors, why wouldn't the std ones be used?

Dont re use the old ones. Best not to play around with fueling type seals....dont wanna hear any bangs from a leaky injector
