I have a question regarding a RR kit from mkm customs, the sinister diesel one. On the blue bypass block that mounts up to the top filter housing, does anyone know the size of threads that are on the inlet side of the block? Im upgrading my feed line to 1/2" and Im wanting to change out the adapter for the stock hard line to one that has a 1/2" JIC or -8an for the inlet.
