Gas tank recommendations?

[1970mcss]

I'm going to finally switch out my gas tank for a vented tank and then possibly add the vaper trapper if the garage gas smell doesn't go away. I'm thinking about a 2 fitting tank unless someone can tell me why I need a 3 line tank. I'm looking for recommendations on which tank to buy and what are recommended vendors. Any other advice would be appreciated.  Thanks

Cant help with the replacement...My original 454 had the 3 port fuel pump, my crate came with a 2 port. I just plugged the return 3rd line and no issues. I did have the "gas smell in the garage" when I replaced the gas tank cap with the wrong type. Correct gas cap fixed that

You will have to check with others on this forum that are smarter than I am, but I believe the three line tanks were from cars manufactured in the California plant, not the Michigan plant.  I have one '71 that was from the California plant and I bought a new tank and sending unit from Summit that worked great.  I believe my other cars from the Michigan plant are two line tanks.

Mine is a a 3 line tank, built in LA and sold to dealer in long beach Ca. Sold to customer in Long beach. Still original fuel lines.

I ended up ordering a tank from summit with 2 vents, thanks for the responses

I ended up installing the new tank with 2 vent pipes. I also installed the factory vent with 2 hoses. What a difference,  the smell is gone and the car seems to run better.
