Man do you have experience! I am impressed...really!
Sorry for being a dick.
Well I guess being seven years since you pulled wrenches at the dealer has made you a little rusty on Ford's changes to fuel management.
No worries. Just go back to the Ford dealer you once worked for and ask to see the Ford Emission and Powertrain Control manual.
Look up Ford return less fuel systems. There it will give an overview of all the components and their operations. Including the operation of the fuel temp sender/elec F.P/Reg
Peace!
ps. No need to drive out to Canada either
