Totally stupid question, and trust me I didn't want to post it as it makes me look really bad, so I did a lot of searching before posting. So bring on the cracks and wise *** remarks after you answer – I feel like I deserve it for asking this one!
On the stock injectors, is the red color top injector the secondary and the tan the primary? Or is it the reverse? In the rush of taking the engine apart for a rebuilt, I noted almost everything else (was more concerned with vacuum lines then fuel) but now that I have them back from cleaning, I cannot remember which one goes where.
Again, these are the stock injectors.
Thanks for answering a question I really didn’t want to ask

 

The long ones are the primaries. The shorter ones are the secondaries.

 

Thanks!
