Make sure the unit your working on is the same design as the spider pictured below, either a V6 or V8

take the injector in one hand and the fuel line in the other, pull the injector off the line.
STEP FOUR :
Inspect the fuel line for any damage, the end of the fuel line will be flared to accept the replacement injector.
shown below is the new injector that you will install on your current fuel line.
STEP FIVE :
Push the replacement injector into your existing fuel line as shown below. You will hear a snap when the injector is seated in the line.
STEP SIX :
slide the plug wire and black protective tubing back down the fuel line, plug the injector back in and push the green tab down to lock the connector.
That's It! repeat these steps for all 6 or 8 injectors. We hope this guide helps you. Good Luck!
