Ok guys just ordered a new set of and injectors and return lines got the injectors in and torqued down and went to put the plastic reurn caps on and they dont seal tight can just slide them up and down with the injection line on it. They came with o rings already installed and i went ahead and changed them to the orings that came in the kit to see if they were different but no luck. Got any ideas?

 

where you get the kit from?
