Primary Injectors
I have an issue with hydro-lock in one of the cylinders and (thanks to ZR-1 Forum advisors) narrowed it down to fuel injectors. I ordered 8 primary injectors and upon removing the fuel rail discovered that the injectors I received look a lot like the secondary injectors and (more significantly) nothing like the primary injectors. One injector has an O-ring top and bottom, the other has only one O-ring on the top with a tapered nozzle. Which on is which? BTW: Atlantic is out of injectors!

Re: Primary Injectors
what injectors did you buy? The OEM primaries are like you said, no o-ring on the bottom, the o-ring stays in the injector housing. So it has a more tapered end since there's no reason not to.

Re: Primary Injectors
Your profile lists your car as a 90 so the primarys should be the tapered style with the O-ring mounted in the injector housing instead of on the injector. The 93-95 model years use the secondary type injectors (O-ring at bottom) all around. This causes a good deal of confusion for both owners and auto parts stores.
