Timing chain and tensioner

Have a 2004 F150 5.4 3v with 208,000 on it. Found I have a bad timing chain tensioner. I have decided I'm going to replace my cam phasers while I have it apart. Since I have the timing chain cover off should i just go ahead and replace the timing chain and or the water pump and oil pump??? Any suggestions would be great.

Water pump is not run by the timing chain. It's directly above the cover. So you can but you don't have to. Each cam actually has it's own chain and tensioner. When you have the cover off you'll see two chains.

To change the oil pump you'd also have to remove the oil pan I believe to be able to get the pickup tube out. So unless you feel like doing that as well then scratch doing the oil pump.

I just swapped one of these engines two days ago at the shop. It broke a timing guide and the shop owner sold the guy a motor. I could've done the repairs but I do what they tell me to do.
