LandYaghtLover,
The 2 lines that are in the way are fuel lines. The one that goes to the a/c hose is the return line. That thing in the a/c hose that it hooks to is a fuel cooler.
Disconnect the 2 fuel lines from the fuel dist. If I remember correctly, use 2 17 mm wrenches, one to hold the adaptor in the fuel dist and the other to remove the hose. Remove the plug wires and lay them out of the way and the cover will come right off. When you replace the valve cover gaskets, get the copper washers that go on the valve cover bolts.
Good luck.
Paul
