Not ALL 2nd gen. Escort 1.9L LX's have an EGR valve & EGR tubing. I know because I have a 92 LX wagon that never had an EGR setup - (its been in the family since new). I also have a 94 Escort LX wagon that does have EGR. Depending on when your car was made, its possible it doesnt have EGR. If so, its one less thing to have to undo and reconnect on the intake manifold.
It also means the original manifold may not have the EGR system, and your replacement manifold might. Or vice versa.
If the engine's exhaust system has the EGR tube, then the replacement manifold would either need to have one or you would need to plug up the fitting on the exhaust system -
and........
1. If they have emissions testing where you live, I think car would fail the test without the EGR working; and 2. The Service Engine Light may keep coming on, since the ECC expects results at the O2 sensor when it opens the EGR valve. The ECC computer has to match the stuff under the hood.

I also have an (early) 91 Escort LX sedan that has the EGR valve and tube, but the EGR tube runs straight down behind the engine and connects into the exhaust pipe downstream of the catalytic converter. !

When I needed to unscrew that EGR tube flare nut, I used a 6 point 1-1/8" box-end wrench, that I had modified. I first ground away enough of the 'box' so it would fit over the EGR tube, then heated the neck of the wrench (with an acetylene torch) enough to bend it up at 90 degrees.
A equally good solution would be to buy a 1-1/8" crowfoot wrench, of the 'flare nut' kind, and of 6 point design, not 12 point. But check the wrench size needed, as Im not sure what size it was either.
And of course to spray the parts with penetrating oil to get it unscrewed, and coat the threads with an antisieze compound when re-installing it.
