Second pic shows the PCV valve in your hand - put it back where it was and leave it alone - messing with this little unit can RUIN your driveability and a bunch of other stuff.
The red hose is indedd the vac source for the FPR.
To find another vaccum source follow the hose of the top of the UIM that ISN'T connected to the Brake Booster - at the end of that black pipe is a "distribution block" for various vacuum sources - take a "T" fitting and put it in line with one of those hose coming out of the distribution block - DON'T use the hoses coming out of the EGR's vacuum solenoid as that green hose to the EGR does not get vacuum all the time.
