So i got two replacement injectors for my 99, and im about to install as soon as i get home. Is there anything i need to know about the install? from what i can tell, i just need to relieve fuel pressure, unbolt the fuel rail, and remove the injectors?

put some o-ring grease on the o-rings on the new injectors before installing them.

One bit of advice is to replace the o-rings whether they look good or not. A touch of some neutral-type grease on each one to help it slip in without getting nicked is a good idea. Sometimes you will find they get stuck and the injector will pull out leaving the o-ring behind. make sure every one is accounted for (top and bottom of every injector) before installing new ones.

They are cheap and replacing them will avoid any potential leaks...

+1,000,000. I couldn't get mine to seat in my 302 engine. I tried and tried, then the little light bulb turned on and told me to used lube.

Lube solves many problems.
