which grommet or air bleed to use???

[Fidelity101]

I have an S5 motor in an S4 car using the S4 electronics and all that boring jazz, so I still use my S4 injectors but I am using S5 rails. so I ordered s5 grommets for my injectors since they were going to be on an S5 block/manifold with s5 rails.

on mazdatrix's website they have the grommets listed as

84-92 All Upper Grommet 13-2520-8574
84-88 All Lower Grommet 13-2570-N326
89-92 All Lower Grommet 13-2570-N350

so I have the right upper grommet but I ordered the bolded grommet for the lower

I have a terrible vacuum leak coming from the primary injectors and the air bleeds are in there.

The 84-88 non turbos use a one piece bleed, while 86-88 turbo and all 89-92 use a two piece bleed (Top & Bottom)

so do I need to put S4 air bleeds in there or did I buy the wrong grommet?
