I purchased 6 used 280 155 746 Bosch fuel injectors for my 1990 Renix XJ from ebay. I bought a new Seal kit for them from O'Rielly and it seemed to be the wrong one and they could not locate the right one. So i went to NAPA and they gave me the same kit, but could not tell me where the parts went.

the kit looks like this.

the plastic "support ring" would seem like it would go on the front to keep the o-ring on, but it doesn't, it just fits REALLY loose and falls when you turn it upside down.

The guys at NAPA said I MIGHT need to put the plastic piece in first and then insert the injector... but if would've went right into my cylinder.

has anyone every ran into this before? I had to put five 746 injectors in and left one old one in, i'm not sure if this is bad to do in the meantime.

Those o-rings are as common as belly buttons.

What are you doing with plastic things?

I do not have a problem finding the o-rings anywhere... but the pintle cap (finally found the name for it) is not in the seal kit.

and autozone, oreilly's or napa cannot find the correct ones in their database.

i'm pretty sure this is it http://injector-rehab.com/shop/Bosch...iner-Flat.html but $7 shipping on a $1 plastic ring.. not cool.

Can you post up a pic of the injectors you got?
