So I just got my injectors back from RC this AM.

Those are some really cool customer oriented guys by the way.

But my question is this, they for got to send the orings for the injectors that go into the engine(not the fuel rail side).
I need to know can I buy these at Truevlaue or HOmedepot or are they some special material that is fuel proof.

If they are regular rubber and I can use homedepot orings, what size do I need?

 

Morris,

To be honest - I would play safe and use the toyota ones. My local Lexus dealer actually had them in stock so I didn't have to wait for them. They are pretty expensive - but for peace of mind worth it.

I am sorry I do not remember the size.

Toyota/Lexus dealer fuel injector O-rings. Nothing else !

The plastics are designed for the use.

 

Yea I found out the hard way (ie legwork) about the orings.

It seems that the folks who installed my last set of injectors used regular circular orings one on top and one on bottom. That did work fine but when I pulled the old ones out I foudn that 3 of hte 8 were damaged. After much searching and research I found that Lexus actually has a barrel shape oring that you are supposed to use. One on top one on bottom and a smal circular oring on the bottom as well.

I got the ones on the bottom in fine but the barrel shaped one for the top wouldnt fit right so I used the standard green oring that I had before for the top where the fuel rail mounted.

Thanks guys, I did get the 440's in by the way. Just took a bit longer than I originally planned.
