lacking power and slightly missing

Hi everyone. Just need some verification on my problem. I have an 03 Pete 6 nz and I’ve been lacking power lately. When I got in yesterday I dropped the primary fuel filter and noticed it was less than half full.truck starts right up, I changed all my lines from and including the diverter valve to the tanks recently. New transfer pump, new check valve, new primer pump, and new vents. Only lines I didn’t change was the line from the diverter valve to the primary filter. If my primary filter is low on fuel I would think it’s draining back to the tanks. Yes, no, anything else I’m missing?

 

I’ve been under the truck with a bunch of wrenches and everything seems tight. Was doing a walk around and noticed that the “e” clip on the waste gate connection to the turbo was gone which caused the rod to fall off. This happened to me last year and I put a handful in my tool box, but didn’t think to check the turbo, even though I thought it sounded different. All is good, plenty of power now. Thank you all for your responses. Keep the shinny side up.

 

I found it. Same problem I had a while back. The e clip fell off the waste gate rod. No turbo power. Isn’t it amazing what a 3 cent part will do. Thanks guys for your comebacks
