Default PE injector o-ring locations?

Please look at the pic & answer accordingly if you have had experence with PE series injectors...

The question is do you reuse the stock lower o-ring on a PE injector?

I have PE 800 cc injectors with Perrin fuel rails. I reused the stock bottom o-rings.

I used the pe injectors with their o-rings and did not have a problem. There is a piece on the stock injector plug that you need to cut off and the pe injectors will snap on and fit the stock fuel rail with no problems. So to answer your question, NO. Just take them out of the box, cut the peice off the stock injector plug, and connect them to the fuel rail.

I just noticed you were talking about the bottom o-ring. For some reason I did not look at the picture. Well, I used the stock bottom o-ring and have not had a problem. It might not be necessary but I used them anyway.

The o-ring in the middle of the body will seal the injector... you do not need to use that seat ring when using the PE injectors.

I assumed that as well...

update: the source (don't ask who... I'm not here to smear names/companies) I had been told by has changed their view & has said it also is not needed... oh well... all's well.

Do not use the lower seal ring. It moves the injector up, and you'll need to shim the rail up with washers to fit semi-right. Also, it moves the tip back into the bore so that the spray cone will(?) wet out on the bore instead of spraying into the airflow. I installed with the seal rings on my first go around, then realized my mistake (and poor idle). I then re-did the job to eliminate the lower ring. The body o-ring seals quite well.

Only use the supplied upper o-ring. It seals with it. You can't use the bottom seal because the injector is longer and wider in that section. I have done it in three cars including my own.
