One would think there must be a fairly good market for a company to make gas tanks for these cars. A year ago when I first bought my '73 240z I looked everywhere on the net for a new aftermarket tank. I saw very many different tanks for many classic models, '34 fords, 55 T-birds, vettes,,you name it, the tanks are out there. At very reasonable prices also. It seemed like most were a little over $100 to $150. Yet we are spending around $300 to have it refurbished by a professional at a radiator shop. Geez, you would think some fabricating shop would catch on and start making them. Why let a professional boil it, acid wash it, rinse it, line it, seal test it, paint it you may ask? Because I'm a firm believer in the fact that you can't beat a man at his own profession.

our cars compared to others you mentioned: look at the production numbers of those detroit greats. now look at the production numbers of carbed 240Z/260Zs. i bet that the detroit cars had more cars made in one year that nissan made in the car's entire run

Also, tooling for gas tanks isn't cheap. There are way too many different tank designs as well since the floor design kept changing over the S30 years. It just wouldn't be profitable. :disappoin

And a large number of 240Zs have rusted to scrap by now. The potential market is far too small to justify the investment.
