I have a 10th anv, 88 Turbo II. I need help with the location of the primary and secondary injectors. Are the primarys on the big or small fuel rail? I thought the secondarys where on the big fuel rail. Thanks for any info you can give me.

 

Primaries are the ones that attatch straight to the block. Secondaries are on the Intake Manifold.

As least thats how it is on my 89 TII

 

so straight to the block with the small fuel rail are the primaries and to the manifold with the big fuel rail (spaced farther apart) are the secondaries YES?

 

Yes
