Hey HT, i'm in the process of buying used RC 550 injectors. My question is, will they fit a B-series fuel rail, but we originally on a K-series fuel rail?

I posted this in Tech/misc but didn't get a response, Thanks again guys.

 

According to my conversations with precision turbo, K series injectors are a tad different. They've got bigger o-rings on the top of them... precision recommends using their "domestic" injectors for the K. Seems like the only major difference is the o-ring. Swap it and see if it fits.
