Re: Correct 72 EEC reproduction gas tank w 1 1/2 inch neck
Here's the information needed to find & purchase one for the 1972 EEC tank. This cap still vents in other than ordinary circumstances but it is a safety requirement mandated by the Federal government. Due to the following

OE Vacuum relief prevents fuel vapors from exiting the fuel system via the fill tube under normal operations. This allows an alternative path for air to flow into the tank if there is an obstruction in the vapor recovery or vapor management systems. Permits pressure to escape if the vapor management system malfunctions.

Part Number: 10704
Features: OE Equivalent Fuel Cap
A "Torque Override" feature aids in the proper installation of the fuel cap. It produces an audible click as the o-ring that seals the cap is properly compressed.

A "Breakaway Groove" allows the cap to remain sealed and prevent fuel leakage during a crash or impact, even if some of the cap has broken away.
OE Pressure relief prevents fuel vapors from exiting the fuel system under normal operating conditions. This allows an escape path for pressure in the event of an impact situation where the fuel tank has collapsed.
Permits pressure to escape if the vapor management system malfunctions.
A "Lost Motion" feature permits the cap handle some freedom to turn while maintaining a seal, which could aid in the prevention of fuel tank leakage during a crash or impact.

We do not sell the cap so you'll need to order 1 online or pickup at a local auto parts store. Nor do we sell these incorrectly made 1972 EEC tanks. Currently no one reproduces a correct 72 EEC tank with the correct 1 1/2" fuel filler neck, when or if they make it correctly we'll then carry the tank.
