New, OEM Power valve 16059-n3314 (F-1/R-1, third series w/green paint) for 1973/1974 Datsun 240Z/260Z models with OEM “flat top” Hitachi SU carburetors. Last and most improved, modified design of the 3 that Nissan developed to fit 73-74 Datsun SU carburetors. These rare to find, OEM power valves, have been NLA for many years now.
Note: Price is for one power valve, not a pair, as pictured. This NOS power valve design is one of 2 that make a matched set. pn for other one is 16059-n3313. It can still be beneficial to install just one improved power valve to an aged set of SU flat tops.
If you have original “flat top” SU carburetors on your Z and they are running rich or very poorly and you can not find anyone to rebuild them, quite often these problems are related to older design power valves. These mount on the side of the carburetor where they can easily be replaced without having to remove or disassemble the entire carburetor.
Nissan describes 3 variations or evolutions of design of these power valves and how to ID them in a Tech supplement for dealerships entitled”1973 240Z/1974 260Z Fuel System Modification Plus” You can download a copy HERE
