    Hi, the vacuum secondaries are designed to open when additional airflow is needed to meet demand. If your RPMs are too low, opening the secondaries will not increase horsepower. If you really want all barrels to open when you floor it, you will need to get a different carb with mechanical secondaries.

Carburetor on my 85 Deville only one injector works what could be the problem

There may not be anything wrong. On a two-injector throttle body, the second injector acts similarly to a four barrel carburetor. On a four barrel, only two barrels supply fuel until you kick the accelerator pedal down hard for quick power for passing as such. At idle or normal cruise the second injector in non-operable. Only when you kick the pedal down (passing gear in old school terms), does the second injector activate.

Where is the main fuel line intake on my holly 4 barrel carb?

If it has a hose hookup you attach it there with a clamp or if you do not have the proper fitting or fuel line end you will have to get the proper parts.

86 ford 460 cu. in. Ford w/ Holly four barrle carborator secondary

On most models, the secondary barrels would only work if the primary are in wide open position, and even then the range of opening is small.
The engine should run past 3000 RPM on just the front barrels, so you may have something else going on.

Carberator problem - holly carb on chevy 350 motor

You are correct, there is a float inside a holley 4 barrel fuel bowl.
Is the electric fuel pump regulated? If the fuel pressure is above 8 lbs, you could run into this issue or the float / needle / seat could have a problem or miss adjusted.

By the way, a 2007 GMC is not carbureted so I assume this is not the vehicle or it has been modified.

Good luck.
