420A Stock Fuel Injector O-ring replacement Eclipse 99 RS 420a

[Raider_831]

Hello, I have a stock 1999 Mitsubishi Eclipse RS. About to hit 200k miles. I recently got flashing p0304 code. My spark plugs look good, spark plugs wires look good and both aren’t old less than 1 year. So my next step is to test my injectors to see if they’re the issue. But I was recommended to get the o-ring kit.

My question is do any of you guys know a good place/link to get them that will fit no issues. I know Autozone and O’Rillys will often give wrong parts. And do the injectors need multiple o-rings per injector or different size o rings per injector? I just want to make sure I show up with the correct parts.

I did read the comments on the Autozone and O’Rillys options but non confirmed they fit on a 2g Eclipse.

Thanks in advance.

The o-rings you're looking for are as follows:
0.296" inner diameter
0.574" outer diameter

Do you have experience using the felpro option? That’s the one O’Rillys and Autozone recommended when I put my cars info. I just wanted to verify that is the right size for the 420a stock injectors as they sometimes recommend the wrong parts even if you put the right info. Thanks

FelPro generally distributes a good product. It isn't often that I have issues with any of their seals or gaskets. I typically prefer their headgaskets over other aftermarket brands, where an original manufacturer part is unavailable.

I’ve used felpro for the valve cover gasket on the car. But this will be my first time servicing the injectors to see if they’re the ones causing issues. Thanks
