Fuel Injector Installation

[sswalker]

I need to put a new fuel injector in my 2003 GMC Sierra with the 5.3 engine (#8 cylinder). Any tips, tricks, or instructions for me on this? Is it something I can do on my own or should I not even be attemping it?

 

Any help is appreciated.

Thanks,

Scott

Simple really....pull off fuel rail...pull out old injector ensuring both top and bottom o-rings come out too...install new o-rings on new injector...add a little o-ring lube or petrolum jelly on them...insert new injector in rail, lower rail and ensure all injectors seat....re install parts you had to remove off the top end to get at fuel rail....start it up and check for leaks.

Thanks for the help. I guess I should have looked at it before I posted. It was pretty simple to do. Got it in. Biggest problem was figuring out how the injector came unplugged and then unclipping it from the rail. Once I figured that out it was pretty simple. Now hopefully that fixes my problem.
