Question about Nissan 240SX
I checked the fuel line for any leaks but i cant find any leaks and the hoses looks pretty good
The carbon canister may saturated. If you are one to try get as much fuel as possible into the fuel tank, that may be how it happened.
Also check the gas cap. There is supposed to be a one way valve to allow air to enter into tank, but not vent out in any direction but by the vent hose to the carbon canister. That valve may be leaking. Also, there is a purge vent to the intake manifold, check to make sure that passage is clear and not carboned up.

Your EVAP system includes all of the connecting EVAP hoses and lines (NOT the fuel lines - you are looking for a vapor leak, not a fuel leak). It also includes the fuel tank, all of the fuel tank grommets and gaskets, charcoal canister, fuel filler tube, fuel cap, purge valve and vent control valve. The failure may be mechanical or electrical in nature. The system needs to be properly diagnosed.

Running out of power going up a hill is generally the fuel pump. Now days a plugged catalytic converter will do it also. The fuel evaporation test could be a bad gas cap or evaporation canister or hose somewhere. The exhaust manifold is a jeep thing, expansion and contraction, hot cold over and over. Have it welded or replaced.

EVAP is evaporative emissions which include the raw fuel vapors from the tank. They are known as hydrocarbons. The evap system contains these vapors and disposes of them through the burning process in the engine. You have valves and solenoids controlled by the computer to purge them from the system. Some of the parts that may cause this test to fail are the vapor lines to and from the tank, the fuel cap (loose or leaking), the carbon canister, and the purge valve or solenoid. It is a somewhat difficult system to test because it is under very low pressure. With all the components in the system, it is hard to say which is at fault. There is a pressure tester provided by Rotunda (Ford service tool) that is made to diagnose this particular problem. You local dealer should have one. About all you can do yourself is visually check the lines and the fuel cap for obvious problems. The MIL light may be on for this reason also. I hope this helps.
