Bleed off fuel pressure.
Seperate the quick disconnect (fuel line to fuel rail). Remove electrical connectors at each injector.
Remove hold down bolts on fuel rail.
Lift rail with injectors attatched.

Follow rangers instructions. They're exactly right....but the injectors are pretty stiff to get out......You WILL have to work at them for a lil bit.

Someone help me here. How does changing valve covers increase oil pressure?

Ranger-How do you relieve the fuel pressure? Is there a valve on the fuel rail somewhere?

Yes, look for a schreader valve on the end of the left bank fuel rail. Looks just like a tire valve. Hold a rag over the valve when you depress it as you'll get gas out of it. An ounce or so I would guess.

Wait... does he also have to depressurize the fuel system by removing the fuse and whatever?

That'* the alternative method. Pull the fuel pump fuse and crank the engine.

I didn't think replacing the value conver gasket would either,but it did increase the lowed oil pressure instead of runnig at 35-37 it now never get less then 42-44
