Hi I’m new to the whole posting in a forum, usually I just read them and go about my way but I can’t find anything similar to my issue, 09 crapforce 13 idles fine but when you give her throttle she bogs down and fills the bay up with white smoke, smell of rich burning fuel aswell. Just did a head job the whole 9 yards, decked, pressure tested, and almost just about anything on head is new. Adjusted valves and everything according to manufacture spec. All fuel data looks fine on diag software, I need some ideas of what else to check, originally thought previous mechanic did the valve adjustment wrong issue still consists
Maxxforce 13 no power on accel

My bad.
White smoke + low power makes me think air is getting into the fuel system.Yippykyae and blairandgretchen Thank this. -
I forgot to mention the truck is deleted aswell. I bypassed the Davco filter and the primer bowl, hooked a hose up from the lift pump to a bucket a fuel, no change in the truck whatsoever, it has a new lift pump and high pressure pump too

Also
Also new did the fuel line kit that came with new tubes to the injectors themselves -
Have you found the problem yet. I have a 2012 Maxforce 13 with the same symptoms. Low power, Hesitation on throttle up and white smoke. I found aeration in the fuel primer bowl and have traced it to the Davco filter. I have tried everything and cannot get it to stop sucking air. I ran the fuel straight in to the primer once and it ran much better with no aeration.
