I have replaced the whole intake without disconnecting the fuel line, but it is nice to get it completely out of the way.

You don't need to disconnect the fuel line.
Bleed the fuel pressure via the shrader valve at the front left end of the rail. Remove the 4 rail hold down bolts, Lift one side of the rail (the injectors will pop out out of the manifold with it), slide the cover in place, and carefully press rail and injectors back into place. Replace bolts, and done.
If you really want to disconnect the fuel line, it's a 3/8".

Was out in the garage putting on some of the painted plastic/fiberglass underhood parts that I recently bought and when I got to the Plenum cover I found that inorder to install it I need to remove the fuel rails and crossover tube. Does anyone know what size the tool is to disconnect the fuel line? I will need to purchase one and from what I found online they come in many different sizes from 5/16 up to 7/8. I don't want to buy the full set that is available but would prefer to buy just one or two sizes. Anyone who has removed the rails remember what size the tool is????
TIA, Chuck S.

I was under the impression you could just remove the 4 bolts and pull each side of the fuel rail assy up and then put the plenum cover on and reinstall the fuel rails without having to disconnect the fuel line. Just make sure to put a dab of oil on the injector O-rings before reinstalling them.

Here's a thread I posted on upgrading fuel injectors that shows removal of the fuel rail.
