I made this with my mom when her gas tank flap broke and the auto repair shop said it would cost 150$ to repair. This project will save you a lot of money if you have a broken gas tank flap. The answer was after many trial and error experiments magnets that one was the only one that worked.
Step 1: Gathering Materials
There is only one material:
Magnets (with a sticky side)
Step 2: Putting on the Magnets
Put on the magnets on the end of the gas tank.
Step 3: You Did It!!!!
Good Job you're done I hope this project worked out for you.
