i am glad the bulb is not out because as someone posted somewhere there is no way to get to the bulb

 

I was curious about this and I missed the section of the service manual where you could just short the two wires together at the sensor to test it so I pulled the gauges apart and the low fuel light is in fact not one but a pair of LEDs!

 

Just to add to this testing discussion - the light is not instant when you join the wires to test it.

It has a delay timer in the clocks - the light can take a minute to come on after the wires are joined together.

 

can anyone tell me which wire goes where lol I took the tank off and dont know if I hooked it back up right, will not know until a while lol which color goes towards the front of the bike? Thanks guys this would save me some time.

 

If I remember right, it didnt really matter where the wires hooked up. It should be just like a light switch. It will work either way.

 

ok thanks

 

the sensor in the tank i's called a thermistor and after much searching online and several fruitless aggravating phone calls with parts houses I finally found one on eBay that was listed for 69 to 73 mustangs and cougars. The item number on eBay is 372154702745, it is absolutely identical to the sensor in our fuel tanks so the only thing you'll have to do to put it in your bike is unsolder the old one from the bracket then put the new one in the bracket and resolder it and then remount the bracket onto the fuel pump assembly and connect the wire.
