Sandy455 Posted October 30 Share Posted October 30 (edited) Have been driving my 1970 240Z on the street and track for 12+ years. I've replaced the seal and stock gas cap over the years. But getting the cap 100% screwed down is always a challenge. And there have been times I was sure it was fully closed but it wasn't and had fuel leakage down the rear fender during time trials. To that end, anyone out there installed a more modern/aircraft style fuel cap with a new fuel filler opening? Thanks.

jhm Posted October 31 Share Posted October 31 I have seen some folks add a Ferrrari-style "pop-up" gas cap and filler; but it's not a trivial mod cost- or work-wise. And it's usually done for asthetics vs functionality, IME. I'm curious....are you using this style cap? It's what I use; and have no problem with spillage/leakage at the track, even when the tank is fairly full. https://www.zeddsaver.com/collections/gas-caps/products/240z-280z-gas-cap-with-retainer-ring I'm interested to see what other folks have to say -- following. Hope you find a solution that works for you!! Quote Link to comment Share on other sites More sharing options...
Sandy455 Posted October 31 Author Share Posted October 31 Yes. That's the set up I have now. But as I'm hearing from different folks in my Datsun world since I posted this, replacing the inlet/ring to something else is extremely pricey. 1 Quote Link to comment Share on other sites More sharing options...
darom Posted yesterday at 05:03 PM Share Posted yesterday at 05:03 PM I bought a gas cap for a 2002 bmw for my 280z (MSA used to sell them, it is showing out of stock: https://www.thezstore.com/product/4445/locking-gas-cap-70-76-240z-260z-280z ) The cap fits tight. Not sure if this is something that will work for your racing events. Quote Link to comment Share on other sites More sharing options...
Sandy455 Posted 3 hours ago Author Share Posted 3 hours ago Thank you for your response but I'm a little confused... You bought a 280Z gas cap for your BMW? Or you bought one of those locking models for both cars? Either way, yes, still out of stock. Quote Link to comment Share on other sites More sharing options...
darom Posted 3 hours ago Share Posted 3 hours ago Sorry about the confusion. I bought a 2002 bmw gas cap which I installed on my '76 280z. Quote Link to comment Share on other sites More sharing options...
Sandy455 Posted 2 hours ago Author Share Posted 2 hours ago Okay. Sorry. But now I'm doubly confused. The out of stock locking cap you posted is for a 280Z, right? Where is the 2002 cap you purchased? Quote Link to comment Share on other sites More sharing options...
Mitchel0407 Posted 1 hour ago Share Posted 1 hour ago As I understand it he needed a new gas cap for his 1976 280z and found a gas cap from a 2002 BMW that fit his 280z Understand that in general engineers are lazy people (I could know, I am one) and the wheel can only be invented so many times before you start making similar products. So no I don’t find it weird at all that a gas cap from a 2002 BMW happens to fit on a 1976 Datsun 280z. Hell my 1977 280z is running a AFM from a 1996 Mazda 626! 😂 Quote Link to comment Share on other sites More sharing options...
Sandy455 Posted 1 hour ago Author Share Posted 1 hour ago (edited) Yes. Thank you. Looking forward to his reply on that 2002 cap. Edited 1 hour ago by Sandy455 Quote Link to comment Share on other sites More sharing options...
