So I'm unclear about the mod instructions on rotaryheads.com, to make Bosch 1600s fit the s5 fuel rail. I've already ground off the top plastic on the rail. It's the orings I'm confused about.

I bought the 82 VW Rabbit injector o rings like they used in the Tutorial. The problem is, they say to use 2 on the bottom, but only 1 fits. I suppose I could fit 2 but I would have to pry the bottom cap off, and I'm not sure if it even comes off.






Here's a pic of 1 o ring on it.







Here's a pic of both injectors.







Any insight will be greatly appreciated.

 

Nvm. They come in the rebuild kit, so they must be removeable.
