The original console gauges found in the 1967-1969 Camaro are a really desirable option these days. Unfortunately, moving the fuel gauge down to the console made it hard to see. GM engineers decided to offer a low fuel warning light/module to the Camaro starting in 1967. UPC option U17, the Camaro received a light in the dash that would come on at 1/8 of a tank. This continued under the same U17 option code in 1968-69 with the Camaro low fuel warning module putting out a different signal.

Important Info

Important information to remember when dealing with Camaro low fuel warning modules: The 1967 Camaro low fuel warning module GM part # 1596341 sends a (+) positive signal to the bulb. Meanwhile, the 1968 and 1969 Camaro low fuel warning module GM part # 1596409 sends a (-) ground signal to the bulb. The bulb in the dash on a 1969 Camaro is in the instrument cluster and plugs right in. However, the 1967-68 Camaro requires changing the dash lens to “FUEL”. The 1967 Camaro is also different because the wiring pigtail is exclusive to the 1967 Camaro and tough to find. 

 

Fix it

We shot this 5 minute video for Classic Headquarters a while back. It should clear up some misconceptions or problems created by trying to install a low fuel warning module to your existing gauges. This video should clear up any issues you may have with a new Camaro low fuel warning module installation as well. Since this video was made, we forgot to mention the 1967 Camaro ground wire does attach directly to the ground on the back of the gauge. If you have any questions email or call us! We’re here to help. The procedure detailed here will also work for 1968-72 Nova console gauges as well.

The Camaro Fuel Gauge Mystery

The Camaro fuel gauge can be a mystery…

It can also make you the customer pull your hair out in frustration. But, The experts at Midnight Oil compiled information for an automotive publication which covered GM fuel gauges. It doesn’t matter which GM car or truck you have. The fuel gauges are basically the same. The fuel gauge may be turned sideways or have an extra ground. But, the same three prongs on the back are all the same for all GM cars and trucks. An ignition hot, a ground and a sender signal make up those connections on the back of the Camaro fuel gauge just like all other GM cars and trucks.

Since Midnight Oil specializes in restoration correct parts for the Camaro, it makes sense for us to focus on the Camaro fuel gauge. That is OK because the information on the Camaro fuel gauge can be used to diagnose and fix all other GM fuel gauges. After 1965, GM changed the gauge from 0-30 ohm to 0-90 ohm to improve accuracy. Think of going around a turn and watching the fuel gauge needle move.

Rather than writing this all out in a blog post… We shot this video for Classic Headquarters a few years back. The video is a little over 20 minutes long and covers all reproduction, AC Delco replacement and original fuel gauges. Shown in the video are several different GM fuel gauges and their configuration. It also covers those mysterious resistors found on the back of all GM fuel gauges. If you are having issues with your Camaro fuel gauge, the information contained here is extremely helpful. So, before you pony up big bucks to have have a restoration shop fix it, check out our video below. So, roll up your sleeves, get your hands dirty and fix your Camaro fuel gauge! Enjoy.
