99 Sierra Fue Gauge

My Fuel gauge has been acting up lately, jumping around(from 1/4 tank to 3/4 tank) while driving down the road. It's tough to know how much fuel I really have. Does anyone know where the sending unit is located? Is it easy to change?

Thanks in Advance, -a12vman

Yup, the entire assembly is in the tank. The good news is that you have to replace the entire unit, pump and all, which will run you about 300 bucks.

Oh, yeah. Not real hard to change. You'll have to drop the tank or remove (or shift) the bed To drop the tank, you'll also have to remove the evap canister. If you have a Haynes or Chiltons the instructions are very well detailed and easy to follow. I dropped mine on my 99 Silvy (same truck) replaced it and had it back up and running in about 2.5 hours.

why not just reset your trip meter when you fuel up... and then fuel again when you hit 500KM or 300miles or whatever?

I did that for a long time and got very lucky. The problem is that his pump is going to fail at some time, so if he is having problems now, fix it and get it over with.

I've been resetting my odometer for about 3 years. I bought a new fuel pump cause I just knew it was about to go. The truck now has 197k miles and the pump hasn't quit yet. Of course, it is about the time of the year for snow and cold weather, so I'm probably about done with the luck factor. I'll run it till it drops though.

I was resetting my trip meter too, for about 2.5 years or so with no indication of a problem, then one morning on the way to work, the truck faultered, then died and would not restart. Care to guess what the problem was? So on top of my time (luckily I know how to change one out) the cost of the new pump and the toying fees, my laziness cost me a day off from work with no pay.

I am not saying that you can't get a few years out of it like this, but my experience tells me that smart money is to fix it properly now and say yourself the headaches when you may be broken down on the interstate some where..
