I already did a search on this and found a picture of the low fuel sensor. I was wondering if I should check some other wiring behind the dash or if there was a dedicated fuse for the dash light. I has never worked in my 91' pickup. I bought it used.

Any advice? I would really prefer not to open up the gas tank to check the sensor.

Thanks,
David

 

Depending on the model of your '91 it may never have had it. My '92 Deluxe did not have that option, but the light was in the dash.

 

Same here...I had a PreRunner, 99 model, and it had a light in the dash but it was not functional The dealer replaced 2 fuel sending units and then decided to look it up and found that I didn't have a light. If I had yotatech back then, I would have never gone to the dealer.

 

I thought I ran empty when I first got it. I filled up and it took 12.5 gallons

Then later somehow I managed to fill 13 gallons.

So I looked in my manual and it said I had 17.2 gallons. I thought they were crazy because the gauge was empty.

Then one day I guess I forgot to check the gauge and suddenly a light popped on. I didn't even know I had it. I filled up and it took 16.5 gallons.

My point is maybe you're not running your tank low enough. Just a thought

 

Rofl...I found the bottom of the tank a few weeks ago. I forgot to get gas the week before....looked down and saw the needle buried below the E. Stopped at the gas station and promptly filled it with 17.49 gallons...in a 17.5 gal tank!

I was running on fumes man.
