With cold oil and a quick changeout you might lose less than 4 oz.

On that vehicle it should be located on the oil filter housing.
It'll be behind the alternator. Oil loss will be minimal.

And leave the oil fill cap and dipstick in place so you don't let air in.
There's maybe 1 PSI of pressure pushing the oil out.

The top of the engine isn't at a vacuum so there's nothing you can do to slow the flow.

Pretty sure that sensor is above the level of the oil in the oil pan so there shouldn't be a lot of oil coming out. I would plan on changing it quickly.

Depending on what the dipstick tells you, jacking up the truck on one end or one side or parking on a hill may insure the oil surface is below the sending unit opening.

I was on a slight incline and no oil leaked.

A couple of notes:
The oil sender is located kind of elevated behind the alternator on the engine block.

Also it is angled towards the front passenger tire and not square to the engine block.

Yours may also have electrical tape around the sensor and wires and will require you to cut the tape to pull/remove the connector.

A 22mm deep socket.and ratchet will get the sensor out.

Thanks to all for the advice and help.
