J240ZTurbo Posted June 29, 2010 Share Posted June 29, 2010 (edited) Got a 280z gas tank for my 240z Turbo swap, I see four cables from the 240z harness and only one plug from the 280z tank, does anyone know how these go connected to the 280z tank?

If I understand your questions, you have four wires on the 240z chassis: two are clips for the fuel tank gauge; the other two are actually a negative and positive lines for JDM electric fuel pump. They were not used until the 260Z. You will also have two threaded blind nuts on your 240Z chassis on the passenger side up above the mustache bar that were used to mount the electric fuel pump. The 280Z fuel tank gauge sender terminates in a plastic female fitting. That plastic plug should have four (if my memory is correct) female pins. Two of these are for the fuel tank gauge and the other two are for the low tank signal. You know that yellow or red light that comes on when you a getting low on fuel. The 240z fuel tank gauge sender will replace the 280z sender without modification. Be sure you have a good, if not fresh, "O" ring.

Tony D Posted November 21, 2010 Share Posted November 21, 2010 I'm on the last line: Swap the sender from the tank you removed and your problem is solved: instant compatibility! They are direct swappable with the ring removed. Quote Link to comment Share on other sites More sharing options...
