Diesel fuel orange only on left side and truck misses after 10ibs of boost (c15)

You fuel return to the left tank might be slightly lower then the one to the right tank and with water being heavier then fuel it will follow the lower path. When you fueled up last did you fill both tanks?

 

So that should rule out any water coming from the fuel station cause it would be in both tanks.

 

Any fuel heaters inline or in the tanks?

 

Satellite hose’s are hard piped underneath the concrete pad from the main pump after the meter.

 

Normally fuel heaters are part of the filter bases. I've seen some that are electric and others that circulate coolant through them. If they're in the tank it'd just be a probe threaded into the tank with 2 heater hoses plumbed in.
