YOU CAN NOT USE YOUR OEM INJECTORS IN COMBINATION WITH THE KGPARTS FC OR RE RAILS.
Trying to use the OEM injectors will be at your own risk. I have seen people do this to save a few bucks on buying a Bosch style injector. THE RAIL IS NOT MADE TO ACCEPT OEM INJECTORS.
Putting a larger o-ring to seal the injector into the rail "can" seal the o-ring, BUT it also "can" lead to a HUGE problem latter on. The Bosch style (American) injectors have a much larger ledge to hold the o-ring in place. Putting this same, much larger o-ring on a denso style injector can lead to the o-ring rolling over the ledge as it is about 3 times larger than the ledge on the injector. It may seal at idle with a lower base fuel pressure, but one you start driving, getting into boost, increasing the pressure, there is basically nothing to hold that o-ring IN the rail creating the seal. Do you really want to risk the o-ring rolling over, causing a fuel leak while the fuel pressure is increased spewing fuel all over a hot engine bay? If so, again, do it at your own risk.
If you do want to replace the o-ring, as stated, you can pick them up almost anywhere as it would be a standard replacement for most any American injector.
I would NOT recommend doing it, but if you are going to be suborn about it, I have seen people use several o-rings on the lower portion of the top of a denso injector to build up the missing ledge. Again, I am not recommending it, but if you are going to be "smarter" than everyone else, be safe.
