UNDER THE STRAW HAT – Restorer’s Insight Many Corvettes from this era have had engine or fuel tank swaps. Always inspect your existing tank before ordering to ensure correct configuration—particularly fuel return and vapor port placement.
Installation Note All new fuel tanks are coated with a rust-inhibiting preservative on the interior. This protective lining must be removed prior to use to avoid clogging carburetors or fuel injection systems.
Fuel Tank Prep Procedure • Seal all openings with rags and duct tape • Add cleaner (Acetone, MEK, or Carb Cleaner) • Drop in small hardware (nuts, bolts, washers) • Shake vigorously to agitate and dissolve coating • Repeat until liquid drains clear • Remove all contents and allow tank to fully dry
For best results, always prep before install. A clean tank ensures consistent fuel delivery and long-term performance.
