The fuel rail bolts to the intake per mounting tabs on it, remove them and work the injectors out of the intake, you must disconnect the fuel supply line at the fuel rail fitting, the oil pressure sender can be replaced without removing the intake/ fuel rail, its a pain in the azz but it can be done with the proper socket. There is one made to fit it. The other way is to disconnect the fuel line from the fuel rail and remove the intake manifold with fuel rail still bolted down to it, there are a few vacuum lines on the back of it, be careful not to break the nipples they connect to. I'm sure there are how to videos out there if you can't relate to what i'm saying.

So that was a trick question, In your situation it might be best to take it to a mechanic, If you don't have someone to help you.

Since everyone wants to beat around the bush or be a smartass, here's how you remove the fuel rail.

1. Best to let the car sit overnight if you can. This will allow fuel pressure to naturally bleed off. If you can't do that, you can depressurize the rail using the schrader valve towards the front of the rail. Have some rags handy to catch spilled fuel.
2. Disconnect the metal retaining clip that holds the fuel hose on the driver's side of the fuel rail
3. Using a fuel line disconnect tool (usually colored blue in those color-coded sets) disconnect the fuel line from the rail. Have the rags ready to catch more fuel.
4. Disconnect the 8x fuel injector harness plugs from the fuel injectors. You will likely need a small pick of flat-head screwdriver to disengage the retaining clip wire
5. Remove the 4 10mm bolts that hold the fuel rail to the intake manifold
6. Lift the fuel rail straight up (as straight as you can). It's all one piece, so the left and right will come together, and the injectors will come out too.
7. Set it aside in a safe, clean location away from any potential ignition source (there will likely still be fuel in the rail).

Now, as far as the necessity of removing it to change your oil pressure sending unit-- some people say yes, some people say no. I've done sending units several times, and I prefer to take the fuel rail off before removing the intake manifold. It's just one less thing to get hung up while I'm wrestling with the intake manifold. Once you have the fuel rail out of the way the intake manifold is a breeze. Disconnect the remaining wire harness plugs from the throttle body, unbolt the manifold, and yank it out of there (without breaking the vacuum nipples on the back).

To de pressurize the fuel line I remove the fuel pump relay and crank the engine over. You need a special tool as mentioned above to disconnect the line.

He has enough digits to turn bolts, the thumb, nose picking finger and the bird finger is all you need, but a rechargable ratchet works great, also don't forget about the throttle body elec. plug, coolant lines, vacuum hoses air bridge coupler hose.

Napoleon has good advice. Also, don't lose the gaskets that go in the injector electrical connectors.
