Where is the modulator valve located on the transmission in a 1992 Cadillac Deville? And how do you know when the modmodulator is going bad?

Modulator valves affect the shifting. It will shift but at high RPM's. and it will be a hard shift. The valve is near the back end of the transmission. On the passenger side. It is about 3 inches in diameter and the only thing back there that has a vacuum hose going to it. You may want the vacuum line first.

Gas line leak going to front injectors. how do i

I assume the black tubes are flexible hose that goes over the metal tubing, and is held on by crimped clamps?
You have to take the clamps off.
If they are crimped, you have to break them.
The easiest way is usually to put a visegrips pliers on them and rapidly twist back and forth until the metal heats and breaks.
Some crimps require a grinder to remove.
Other clamps simply have a screwdriver slot and unscrew.
It is usually the rubber tubing that needs replacement.
Remember to tell them it is for fuel injection so that they give you reinforced and gas proof replacement hose.

If you have enough room under the car, put a wet towel by the rusty bolts and around the area. You will have to saw off the rusty bolts. The wet towel will catch sparks coming off the saw blade. Cut off the leaking metal-line, and replace with a good hose.
You could get new metal straps for the dealer.

Transmission leaking

Using rubber hose on cooler line is generally a temporary repair. but if you need to use it put several clamps on and locate screw parts 180 degrees from adjacent clamp. (sometimes slightly flairing the end of the metal line very slightly will keep hose from sliding off.)

Gas line is leaking very close to tank. The leak is at the joint where the metal pipe coming from tank meets a rubber hose that runs to filter. It seems to be leaking right at this joint which seems to...

You want to be very careful not to make any sparks while working on this. The obvious is smoking, banging metal tools around, etc. keep cell phones AWAY from the area. Pick up some rubber fuel line from the parts store. Be prepared for some gas leakage, have a plastic pan under the leak. Disconnect the line at the tank, have a piece of new hose ready to push on over the line to as close to the tank as you can, have the end away from the tank plugged up temporarily with a pencil or something that fits snug in it, then remove the rubber hose on the filter, and connect new line from tank to filter, check for leaks, hopefully it is the rubber line you replaced, or the end of the metal line, so the new hose will hopefully cover the corroded leaking area. Clamp and Dry off area and see if you can spot any leaks.
