89-91 rx7 13b Injectors quick question
 

I know this is a stupid question, but I own a 1991 mazda rx7. Do the oem fuel injectors in the primary fuel rail differ at all from the injectors in the secondary fuel rail? I am replacing the set, but I'm not sure if they go on in a specific order.

Thanks!

this might help you understand the primary/secondary injectors..
