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?

 

Have you changed the secondary filter? I would do that one also.

 

Occasionally when you change a Bunch of lines one can leak air in.Not necessarily leak fuel,but suck a little air in just Enough to screw everything up .JMO

 

Only time I've typically seen partially full fuel filters is when there was a restriction in the system before the filter.

 

Yeah sounds like you have a leak somewhere in the system from your tank to your primary. Gonna have to chase that line. If the secondary was half full, your truck wouldn’t be starting without using your manual primer. I don’t suspect you have any issues with your secondary fuel base, primer or check valve. If so, like I said your secondary would be half full and your truck won’t start. So maybe you have a hose fitting loose and it’s allowing the fuel to bleed back to tank

 

The little dime sized check valves in the primer pump housing can also somehow flip over and cause problems. Easy to check and fix if this is the case.

 

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.

 

What about your fuel filter draining?

 

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

 

Sounds like Me on my date last week.
