so i just got my sl2-240 rc 240cc injectors and the tops look very bulky and big and i’m worried they won’t fit on my fuel rail. i’m going to try to see if they work sunday but i just wanted to see if there are any adapters or anything to make them work on the rail i have. i ran rc 750s on a turbo setup a couple years back. these just look a little different

 

That looks like a "K" series top or equivalent... what made you purchase this part number for a "B" series in the first place ?

 

i looked up rc 240cc injectors for b series and it showed me these ones or 310cc ones identical

 

You must have missed something... those will NOT fit a "B" series engine. I didn't find an application guide on RC's website, so I am not sure where you discovered your information. With RC's, the first three digits of the part number will represent the fitment.

 

You might be able to use these top hats if those are indeed for a K series.
