Guchov Posted February 1, 2021 Share #1 Posted February 1, 2021 I have a 1976 280z I am restoring that I have no gas tank for, while I also have a 77 280z with the space saver rear tire well and that car has a nice cleaned gas tank. My questions are: 1. Would drilling out the spot welds and swapping the space saver well into the 76 car allow me to run the 77 gas tank and fuel components in my 76? 2. What straps and modification would I need to do to secure the tank if it fits? 3. Would the stock fuel lines from the 77 fit in my 76 or would I have to modify or create my own lines? 4. Would the fuel filler neck from the 77 line up in the 76 car? Link to comment Share on other sites More sharing options...
Zed Head Posted February 1, 2021 Share #2 Posted February 1, 2021 Here are some part numbers that might help. @Captain Obvious has modified his car in that area and might have some thoughts. http://www.carpartsmanual.com/datsun/Z-1969-1978/engine-280z/fuel-tank/to-jul-76 http://www.carpartsmanual.com/datsun/Z-1969-1978/engine-280z/fuel-tank/from-jul-76 Link to comment Share on other sites More sharing options...
rturbo 930 Posted February 1, 2021 Share #3 Posted February 1, 2021 (edited) That seems like an awful lot of work when you could just sell your tank and buy the correct tank, either used, or new, since there is now a company making new ones, although I don't know if they're making the ones that are exactly identical to a '76 tank since the fuel tanks changed a bit over the years from 70-76. I would also greatly prefer a full size spare over a space saver. Edited February 1, 2021 by rturbo 930 2 Link to comment Share on other sites More sharing options...

(well, not really "for a living" - I'm retired - but that's what I do at the shop most days...) Link to comment Share on other sites More sharing options...
Captain Obvious Posted February 2, 2021 Share #5 Posted February 2, 2021 Agreed as well. There's no way I would swap the 77 spare tub into your 76 just because you've got a good 77 tank there. I've got a 77 and it has the smaller spare tire tub. I'd rather have a full size, full depth tub instead. Link to comment Share on other sites More sharing options...

Those new ones are the 240z tanks and are different shape.. Link to comment Share on other sites More sharing options...
