Re: RC Primary and Secondary difference
The tabs are removed. Same part they just remove the tabs for you. Ive had mine for almost three years now. Pricey but very good injectors

Re: RC Primary and Secondary difference
I need one to complete a set - the only difference I can see is that there's a 'flange' on the injector end of some. Is that the 'tab'?

Re: RC Primary and Secondary difference
Here is an aftermarket injector with tab on and tab removed>>
 These are the primary injectors which require an 'O' seat in the injector housing>>  Here are the primary and secondary injectors which are very different in configuration (on the 1990 MY anyway)>>

Re: RC Primary and Secondary difference
 1991 ZThese are RC Sl4-205s and are called Primary and Secondary with the tabs removed (I think from secondary) as shown by ZR1Vette in his first picture. The tips of the primary and secondary injectors are different as you can see in Polo-1 second picture and in the pictures directly below. I think the primary injectors are on the right in the picture below.

Re: RC Primary and Secondary difference
So just to confirm then, the primaries don't have the flange at the injector end? Like this -

Re: RC Primary and Secondary difference
The images you show are correct... the secondaries have the 'O' ring attached and the primaries require the 'O' ring seat in the injector housing
Here I am removing the 'O' ring out to replace with a new one>>
