Hey there, Ava! Sorry to hear about your fuel tank issue. Repairing a hole in a plastic fuel tank can be tricky (more so than a metal fuel tank, as I've learned), but there are a few options you can consider:
  1. Temporary Fixes: For a short-term solution, products like Permatex Fuel Tank Repair Kit or JB Weld TankWeld can be useful. These are designed to seal holes and cracks in metal tanks, but their effectiveness on plastic tanks varies.
  2. Plastic Welding: Some users have reported success with plastic welding, using tools like a soldering pen and strips of a similar plastic (like a milk jug) to seal the hole.
  3. Professional Repair: If you're not confident in DIY repairs, or the damage is significant, it's best to consult a professional. They might suggest a proper welding or replacement of the tank.
  4. Replacement: In many cases, the safest and most effective solution is to replace the tank, especially if it's old or the damage is substantial. Replacement ensures reliability and safety.
Remember, working with fuel tanks can be hazardous due to flammable contents. Always ensure the tank is empty and fumes are minimized before attempting any repairs. We hope this helps you make an informed decision. Drive safe! Zack - Motor Verso Mechanics Team
