'92 Regal GS Oil Pump Replacement

I have a 1992 Buick Regal GS with the 3.8l engine that needs a new oil pump. I am going to do the job myself and was wondering where I can find step by step instructions for this job. I checked the chiltons manual and it doesn't really explain much. Any help would be appreciated! By the way, this job doesn't seem too difficult........is it????

try alldatadiy.com sign up for that its 24 bucks but well worth it...saves lots of time...i cant count how many times i have used that when i get stuck on a job

Thanks for the help.
I decided I should let someone who knows what he is doing work on it so I took it in to the garage!
