Classic/Antique Car Repair: 87 chevy pickup, airplane glue, chevy pickup

Question
how do i fix the fuel tanks (holes in line to engine) w/o buying a new one?

Answer
There is a product called "Seal-all" made by Ecletic Products (web site seal-all.com) that looks just about like a old tube of airplane glue.

I buy mine at Target or the auto parts store.

It will actually seal a dripping gas leak without clearing the line.
