yes i know exactly, if mastro dosent have them central fl eurocar may, im pretty sure thats where they are leaking since the injector is pretty much sealed all other places. jeff says i have to have the car put together sat to tune sunday if i want to have it running for the awd meet. gd its going to be a long 2 days. lmk if you may be able to come sat and i can call and pay for those o rings if you could bring them, assuming i cant get them at CFEC when i drive by there tomorrow. maybe manny will read this and be able to check on those o rings since i have no clue on a part number. thanks for the help guys. i cant wait to have my car up and running...
