Most Auto Parts Stores should have a complete "Injector O-Ring Kit" Should have 12 o-rings 6 top, 6 bottoms. Buy it, unbolt the fuel rail, pull the injectors and replace all the O-rings. Better safe than sorry and if 1 is leaking now, the others are soon to follow and if fuel starts leaking, fires a prone to happen.

Unless you like this look...

In which case, don't worry, everything will be ok.


BTW when replacing them, you may have the plastic retainer break off.... this is fine, just put the O-ring on and be careful putting the injectors back in, a little lube helps slide them down into place, but the tabs get brittle with age, don't worry if you break a couple. See picture above^^^
