will i be able to....
 

get all the rubber o rings and grommets for my injectors at a place like pep boys? if so, does anyone know exactly what i need for the secondaries on a 91 n/a?

Get 4 "fuel injector kits", all the gaskets, ETC needed to replace all the rubber on them.

@ Least, that's what O'Reillys calls them.

NAPA has what you need, if you take a sample injector to them.

I know thier machine shops that offer injector cleaning have them.
