The reason the fitting is too small is that is the HIGH side fitting ,look for a larger fitting in one of the larger size hoses or tubing

One is the supply line ,the other is the return line and the third line is the vent line that should go the the charcoal canister.

check for a faulty fuel pump relay and fuel pump fuse. if both are ok, check for faulty fuel pump

If you didn't get any fuel coming out then it's a vent line. The other two are the feed and the return fuel lines.

Usually there are three lines. One for the vent, and two for the fuel pump. One of the pump lines is pressure to the injectors and the other is a return line from the injectors. The vent line may not have a clamp on it and it is the smallest of the three.

trace the line, it could be connected to the fuel filter, or a breather, or headed straight for the engine.

Those are vapor return lines. The engine uses some of the fuel, but not all so vapor not used will be sent back the fuel tank and reused by the engine. It's all a part of the emissions operation of the vehicles. Rather than porting the excess fuel into the air like the old vehicles did they created a return line to the tank to save fuel, protect the environment and get you better MPG or Miles Per Gallon.

Hole in the exhaust? you can check this by getting an assistant to hold a rag over the tailpipe while you look for where the smoke is coming out on the pipe.

This is not really a DIY job as there is a requirement to put the exact amount of gas in the system or you create more problems than you solve. Have an accredited ac shop check the system for leaks first and they will put in the right amount of gas according to the pressures in the system.

Mine does that occasionally intermittently but if you look around in the back of the mirror you'll see some wires, those are most likely broken. I had the mirror completely fall off the windshield and had a windshield installation company reattach it because I knew it took a specialty glass glue, well they broke one of the wires but not completely so it shorts out but a wiggle makes the lights come back on and I'm just to busy to take the mirror off the mount and fix it right. You can remove the mirror from the piece that attaches it to the windshield. Check those wires, good luck
