I recently did the por-15 gas tank sealer kit on my gas tank. I managed to let the tank dry without running pipe cleaners through the vent and fuel outlets. The fuel outlet that runs from outside the tank to the bottom of the inside of the tank is clogged pretty badly.
What is the best way to unclog the line, or did I ruin my fuel tank?
The car is a 1972 240z

I used a clothes hanger on an old Subi gas tank that was gummed up. Farmers bailing wire works good too.
