Fuel Tank For 1970 Olds 98 455 Rocket

[BNTZ57RDMASTER]

I am in need of a fuel tank for my 98 convertible and was wondering what the difference is between a tank with EEC and Without EEC. How can I tell if my car has that.

Thanks,

Ed

Hello Ed:

I checked out a site selling replacement fuel tanks: Classic Car Auto Parts. It appears that a GM vehicle of your vintage with EEC (Evaporative Emission Control) has 3 vents on the fuel tank. A non-EEC vehicle has either 1 or 2 vents. I'm not sure where these vents would be located. Obviously they should be on the upper section of the tank or filler neck. Back in those days, the vents were not yet integrated into the sending unit. (?).

Perhaps this folks at this auto parts site might provide more information.

Good Luck,

Paul
