Wow was I suprised. I waited a week before reinstalling the fuel line and filling the tank. Then, 4 days later it's leaking from the same spot. Before I applied the 5200, I cleaned the tank with soap and water and the threads with brake clean. Luckily the fitting just screwed back out. Luckily the 5200 didn't cause any damage because it didn't bond to much of anything. Weird!
