"Again there are Three fuel lines on my car..."

One is the supply from the tank (tank pump) to the main pump. The second is the return line, from the back end of the fuel pressure regulator -- it simply dumps the gas back into the tank. The third is a vent, which goes forward to the charcoal canister.

You can use ordinary Neoprene fuel hose to repair the steel return line. Usually if a little of the steel line has rusted through, the rest is like Swiss cheese and very fragile. It's best to replace it from way up front to way down back -- about 8-10 feet, or so.

"...the fuses in my fuse box didn't seem to do the trick..."

Those fuses work for a European 240, but not North American. It's more reliable to unplug the main pump under the rear seat, driver's side.

"...someone said, intake manifold gasket could be leaking a little and said it was an 'easy' job..."

Relatively easy. But before tearing it apart, try tightening the manifold nuts.
