Fuel gauge problem

[Loren]

Hi I have a 2007 3500 diesel flatbed dump four-wheel drive anyways I have a dual tank system and I eliminated the rear tank .sending units worked in ohms I understand the gas gauge works in volts so I can not use the factory gas gauge but I cannot find a aftermarket gauge that works with 40-250 ohms what can I do?

Put in a single tank tune in the ecm

Put in a single tank tune in the ecm

X2 this is the easiest and cleanest way to do it.

GMDuramax if I program the ECM for a single tank will the ECM send a voltage signal to the factory gauge?

It will work just like a factory truck with a single tank.
