theakerstwo Posted May 24, 2014 Share Posted May 24, 2014 That been done for years.Use one gauge and two sendors with one switch which will be a three way.You select what tank you want to read.That is one at a time.

scottwetzel Posted May 24, 2014 Author Share Posted May 24, 2014 Do u just run the ground wire from the second tank directly to the guage and just have the grounds on top of each other at the guage?

gearhead204 Posted May 24, 2014 Share Posted May 24, 2014 scott you need what I believe is called a three pole double throw switch one pole will go to the gauge,one will go left tank and one right tank. since the switch is double throw it will connect say left tank to gauge then when switch is moved right tank is connected to the gauge hope this helps 2 Quote Link to comment https://www.bigmacktrucks.com/topic/35832-dual-fuel-guages/#findComment-246602 Share on other sites More sharing options...
