I'm a moron okay, I accept that. So by all means make fun of me.

I lost one of the insulators that go between the fuel injector and the intake. Im having a vacuum leak at what appears to be every injector. Im also missing some other miscellaneous parts. The car was an NA converted to a Gen 2 and then had Gen 3 injector/ecu put in by a professional. I've been looking for those seals and bought 2 sets already that were wrong.

I'm looking for a bunch of misc parts too and I'm more than willing to help whomever figure out ways to ship them. I'm willing to drive up to 4hrs to get parts if I can find stuff like a dash, some parts ill have to send pictures of bc I don't know what they are. Mostly looking for the correct seals but parts in general is helpful. I'm located near Greenville SC.

Thank you guys.

The Injectors in my car have a bigger lower diameter around where the insulators. I bought these first but they did not work. It's driving me insane.

So you will need to find the seal that works with the injector and head. Sorry, it wasn't clear this were not stock injector bodies.

3rd gen insulators seem to be 23291-88480. They don't seem to be available from Toyota USA.

As far as I know, they are stock. If not, I did not do it. I have a Gen 3 ecu, 89661-17469, so just give me a part number for proper injectors and seals. I'll just spend the money. I've been looking around a lot and it's just as hard to find stock OEM 540cc (I need these bc of ecu, right?)

Find a local shop that does injector cleaning, they usually have a variety of seals that will likely fit your application

This. They can also make custom ones from solid synthetics (I forget the material name). I had an old speed source kit that had custom made sealing rings.

If they are stock then the stock seals should work. What colour are your injectors?
Yes you need to run the stock injectors for the stock ECU.

I think Prime has a set with everything in it.
