My gas gauge reads full the whole time, I herd of a ground wire problem, and made sure it was grounded good, but that's not the problem. I don't know where to go from here.. Please help!!
That would be difficult to do since the gas is moving around all the time. there are computers that you can mount to give you that information like the ones used in aircraft. The closest you can get to what you want is more a percentage of fuel left in the tank after filling to 100%. That is basically what your vehicle already has. Some of the newer cars do it digitally, but most still use the analog gauge.I'd like to have digtial gas gauge on my TJ. So I could see actual gallons in the tank, but I'd like that on all my vehicles .
