Jim is 100% right.
It's a big job. Here's the process in a nutshell... I don't think I left anything out here...
1-Clam needs to come off or tilt up

and undertray (not diffuser) gotta go too
2- Remove pass side motor mount and mounting post
3- Jack Pass side engine up using board and jack technique on the oil pan and remove belt tensioner pivot bolt (must be done so the bolt can clear the frame.
4- Lower engine back down to normal level
5- Remove harmonic balancer (put in gear, lock parking brake, and use long extension with 1/2" ratchet--- It's tight.)
6-Remove Valve Cover (obviously the coils come out first)
7- Remove timing chain cover
8- Remove timing chain (you'll need to know "the dot procedure" to reinstall the chain. It's really NOT hard.
9-Remove Oil pump housing
10- Disassemble oil pump (you'll need either a 1/4 impact with impact compatible #3 phillips head or impact driver w/ #3PH. The former is better/easier than the latter to break the assembly screws loose)
11- Swap gears with your new circuit worx units. (the easy part)
12- Reverse of above to reassemble.
Sans the clam issue (I refuse to work on cars without clamhinges

), this job took me about 2 hours... Being that this is your first time, expect 4 -6 hours plus the clam stuff.
Hope that helps.
Good luck!

edit: I just saw Jay's post. I agree a big job, but I probably disagree about the engine removal part- But I see your point Jay:up: FWIW- I would rather replace the oil pump than the fuel pump on a 05 car.LOL (I hear the 06 + cars have larger fuel pump openings in the tank than 05 cars. The only bad part about 05 cars!)
