I've tried searching but couldn't find any info for this.

I need to know which way the injectors face? Basically, how the injector clips face in the fuel rail.

Where most of the injectors sit there are two humps which form a groove for the black plastic clip on each injector so I used this to align 3 of them simply by putting each black plastic clip in the grove. However - the fuel rail does not have these indents for the last injector (closest to the rad) so I am unsure which way this injector should be positioned?

 

I actually found the groves on the fuel rail for the last injector (closest to rad) they are on the bottom, unlike the other 3 are on top.

Hope this helps someone out.
