Steel vs Plastic Tanks for Regal
- Steel Tanks: Preferred for classic Regals (especially 1978-1987 Grand National models) due to strength and authenticity.
- Plastic Tanks: Common on later models (1990s–2004) for lighter weight and rust resistance.
Common Issues with Buick Regal Fuel Tanks
- Rust and corrosion on steel tanks (very common on 1970s–1980s models)
