n/a 87 gxl need help locating secondary injectors

I replaced the o rings on my prymary injectors cause i though one of them was leaking but i still have the problem. ive been searching for the secondary injectors to check them out. but i cant seem to be able to locate them. i know the primaries are right under the intake on the passanger side of the engine. (very visible). but i just cant find the secondaries. any pointers are greatly appreciated!!!

The secondary injectors are on the upper intake manifold, directly below the curve of the black intake tube. There is a long fuel rail connecting them. They are positioned above the point at which the intake runners take a 90 degree turn down.

It sounds to me like you changed out the secondaries and not the primaries.

The secondaries are above the primaries, read the above post. The primaries are on the shorter rail, below the secondaries.

The primaries have a spacer that goes in between the primary fuel rail and the block, this must be there or the injectors will leak.

That would be the primaries.
