Buy a repair manual or stop trying because you have NO clue how a car works AT ALL.

all vacuum sources (post throttle body) have the same amount of vacuum so pick one and go. i recommend using the 3/8" hose coming off the FPR that runs to the firewall, i use it on all my cars.

Honestly....the largest vacuum source on a motor is where the intake manifold leads to the brake booster. Many after market vacuum blocks that companies such as FullRace make use the brake booster line as their vacuum source.

There are certain vacuums you want to try your best to avoid using...

One is MAP Sensor.
The 2nd is Fuel Pressure Regulator. If you end up drawing too much vacuum from your fuel pressure regulator it CAN mess up fuel pressure.

Which is exactly why i use the larger of the two hoses on the fuel pressure regulator, its much bigger and has more vacuum.

So can i "T" off the FPR line and run the 3/8" hose to the opening of the GE manifold, then put the fittings in and spit it how ever many times there?
heres a pic of the engine bay and the FPR lines.
