Blue O rings


Recommended Posts

Delco. Say they replace black/brown. Are they OK for fuel injection nozzles ?

It has a lot more to do with what they're made of and a lot less to do with what color they are.

True.  On the Buick 3300 I just repaired, the original o-rings were black. The replacements are an odd almost red color.

 

I always use transmission fluid on my fingers to lubricate the o-rings and injector ports for installation. The o-rings slide on the injectors, and into their bores nicely, and the fluid won't damage the o-rings.
