Were the old ones leaking prior to the replacement?
I would check the throttle body where the injectors mount and be sure there are no remnants of the old o-ring from the old injector.
Are you using lubricant on the o-ring prior to installation?
1. Lubricate new lower (small) o-rings with automatic transmission fluid and push on nozzle end of injector until it presses against injector fuel filter.
2. Install steel injector back up washer in counterbore of fuel meter body.
3. Lubricate new upper (large) o-rings with automatic transmission fluid and install directly over the back up washer. Be sure the o-ring is seated properly and is flush with top of fuel meter body surface.
Note: Backup washers and o-rings must be installed before injectors, or improper seating of large o-rings could cause fuel to leak.
4. Install injector, aligning raised lug on each injector base with notch in fuel meter body cavity. Push down on injector until it is fully seated in the fuel meter body. (Electrical terminals of the injector should be parallel with throttle shaft).
5. Install fuel meter cover gasket.
6. Install fuel meter cover.
7. Reconnect electrical connectors to fuel injectors.
8. With engine "off" and ignition "on", check for fuel leaks.
