Help, i have a small leak that just got worse. I was working on my project car when i noticed a small leak from the gas tank. I checked under the car and i saw where it was leaking from. I touched the line that connects to the gas tank and it was wet with gasoline. I wanted to see if it was tight so i turned it. I continued working on the project not thinking nothing of it cause the leak looked to have stopped. When i started the my car to leave the leak got worse. Instead of a few drops it is consistantly dripping and is near a full stream of fuel. How can i go about fixing this while i still have light. What should i tighten to stop this. There is a nut on the fuel tank side and one on the body side, if i tighten both down and it continues to leak what should i do?

There are two softlines that attach the fuel return and fuel evaporation hardlines to the fuel tank.

Fuel return softline 77049-14040
Fuel evaporation softline 77209-14080

Replace the two softlines, they are probably cracking and you should also replace the clamps with high pressure fuel line clamps. The clamps can be found at any automotive parts store.

The third line is the Fuel feed hardline which goes to the fuel filter and then to the fuel tank but I can't find a part number for the connecting hose.
