This is where the batteries for my camera died. I'll try and get some more ASAP, but this part is pretty basic
Once the assembly is all out, hold on to the fuel rail and twist and pull on the injectors. They should come off with their O-rings. Install your new injectors into the fuel rail with new O-rings, which requires a little lube (oil, nose grease, spit, whatever’s handy). Twist the injector into the fuel rail, kinda screw it in to keep the O-ring from tearing. Same thing on the fuel feed line O-ring too.
Install everything on the reverse order.
Remember the black spacers and the injector insulators.
Torque the fuel rail bolts to (tight) 98 ± 8 in-lb
Torque the fuel feed line bolts to (snug) 44 ± 9 in-lb
Make basic adjustments to your fuel controller if your installing larger than stock injectors.
Once everything is back in, and remember to connect the fuel pump assembly, and start the car. With a flash light look for leaks at the injector ports, along the fuel rail, and the fuel feed and return lines. If you don't see any leaks, and most importantly, you don't smell any fuel, your done.
