which one is the primary injector?
 

i feel really dumb for asking this but is the primary injector the tall one or the short one?

thanks a lot :(

anyone??

There are two primary injectors and two secondary injectors. The primaries are on the driver's side fuel rail.

i know that but i bought new injectors to have them installed but they have to be cleaned first at rc engineering. i want to know which one is the primary. is the the tall one(s) or short one(s)??

the longer ones are the primaries.
