Steel vs Plastic Tanks
- Steel Tanks: Best for classic Skylarks (1953-1980) – stronger, more authentic for restorations, and better for high-performance Gran Sport models.
- Plastic Tanks: Standard on 1985-1998 models for lighter weight and corrosion resistance.
Common Fuel Tank Problems on Buick Skylark
- Rust and pinhole leaks on original steel tanks (very common on 1960s–1970s models)
- Cracking and degradation on plastic tanks (1985–1998)
- Failing sending units causing erratic fuel gauge readings
- Leaking seams, rusted straps, and deteriorated gaskets
