Default injector o-ring question

Hey everyone,

I'm installing DW 650cc injectors along with other stage 3 parts, and I have a question about the o-rings: The stock injectors have a "o-ring"/spacer thing just below the upper o-ring (the fuel rail one). Its got kind of a u-shaped cross section. Google stock wrx injectors and you will see them.

My DW injectors came with just a thicker o-ring where the spacer thing was on the stock injectors. The pics of them on show the o-rings clearly. Which do I use, thicker o-rings or spacer things? The DW injectors have a slightly longer body, and the o-ring they came with is shorter than the spacer, which makes them just about the same length as the stock injectors with the spacer. I'm leaning toward the o-rings that came with the new injectors at this point.

thanks very much for the help
