Guest zarstick Posted September 10, 2006 Share Posted September 10, 2006 Hello, I just replaced my 73 240Z gas tank sending unit with a new one and it does the same as it did before, that is, reads about 1/3 too low. It works but is not accurate, when I fill up the gauge will only read between 1/2 and 3/4 full, when the gauge shows empty there is actually about 1/3 of the tank remaining. Anyone have any ideas? Should I bend the arm on the sending unit to calibrate it? Thanks Quote Link to comment Share on other sites More sharing options...
AK-Z Posted September 11, 2006 Share Posted September 11, 2006 Sounds like the the wires for the fuel sending is starting to more resistence than it should, maybe due to age. Test the wires with a multi-meter. Quote Link to comment Share on other sites More sharing options...
