zigzag240 Posted October 26, 2008 Share Posted October 26, 2008 I searched but not found a definitive answer on this one. On my '70 240 I'd just replaced the stock ammeter/fuel gauge with the voltmeter/fuel gauge from a 75-78 280z. Both had a three wire connector for the fuel gauge portion. The voltmeter part works great. But I'm not getting any fuel level reading at all. Might be a wiring issue, but before I spend a day on it I have to ask the question: Does anyone know if the 240 fuel tank sensor will work properly with a 280Z fuel gauge?

zigzag240 Posted October 26, 2008 Author Share Posted October 26, 2008 I decided that I didn't want to worry about the different resistance values between the tank sensors. So I simply unbolted the fuel gauge from the 240 housing and swapped it into the 280 gauge rear housing. This gives me a 280 housing with a 280 voltmeter on the top and 240 fuel gauge on the bottom....easy. Quote Link to comment Share on other sites More sharing options...
ktm Posted October 26, 2008 Share Posted October 26, 2008 A 280z fuel gauge will work in a 240z. I replaced all of my 240z gauges with 280z gauges. You did more work than was necessary. Quote Link to comment Share on other sites More sharing options...
