Ausz Posted June 12, 2007 Share #1 Posted June 12, 2007 I have 1970 240. Did they come with a secondary fuel tank reservoir located inside the quarter trim and is connected to the fuel tank. If so was there one on just one side or both? Was this aftermarket or stock or dealer option? Link to comment Share on other sites More sharing options...
hls30.com Posted June 12, 2007 Share #2 Posted June 12, 2007 That is an evaprative expansion tank, it is there to cause fuel smells inside the car-actually it is there to allow for fuel expansion and the condensation of vapors to keep them in the real gas tank.Will Link to comment Share on other sites More sharing options...
Ausz Posted June 14, 2007 Author Share #3 Posted June 14, 2007 So original to the early 240s or not? Link to comment Share on other sites More sharing options...
Arne Posted June 14, 2007 Share #4 Posted June 14, 2007 In the USA, yes. It was required for California emissions, so Nissan installed it in all of them. Through 6/71 production it was plastic, after that it was metal.Not certain about the rest of the world. Link to comment Share on other sites More sharing options...
240znz Posted June 14, 2007 Share #5 Posted June 14, 2007 Arne, FWIW my HS30 build date 12/70 does not have the evaporation tank. Can't be sure if this is the is the same for HS30's but I suspect so for the same era delivered to different RHD markets. Link to comment Share on other sites More sharing options...
