Classic Performance aluminum gas tanks fit between the frame rails, are fully baffled, and are compatible with EFI or carburetors. They are made from 0.125 in. 5051 aluminum with 0.187 in. thick brackets and are the thickest on the market. Once installed, the fuel filler can pass through the bed floor, or a custom side fill can be added (requires a small C-notch in the frame). Classic Performance aluminum gas tanks are vehicle specific, install without having to move crossmembers, and you'll end up with a tank that not only looks better, but also helps your car perform better. For your convenience, there are fuel pump options above.
