    The car is a 2000 Cadillac DeVille DTS and it just hit 120,126 miles today. I was looking at rockauto.com(I've used them for many years for multiple cars) and the sensor/cable is anywhere from $110-130. So where do I find this mysterious $30 part haha.
    Get the sk number from rock auto. There will be 2 different options depending on your vin. Use that sk number (mine is sk1035) and search eBay. There are several listed there. Those will be ac delco. For cheaper ones search for deville fuel level sensor.

    Yep. Ebay all the way. The only thing I didn't use any special codes. Nobody nowhere even mentioned them. Even ebay sellers.

    I see several sk1035 listed as well as sk1030. Rock auto shows sk1035, sk1030, and sk1194. The 1194 and 1035 are first and second designs and go by the vin. They both have dual prong locking feature and the 1035 with loose CPA clip (no idea what the CPA clip is). The 1030 has single prong locking feature without loose CPA clip but it doesn't say anything about the vin or first or second design. I need one of these sensors and guess I'm gonna take mine out to see what one I have. Unless y'all's think I should just get the one that says fits my vin, I'm just confused as to whether I need the 1030 or 1035 lol

    Re: Fuel gauge reading wrong.

    Thanks for all the help fellas. After running a few cycles of Techron, it's only a few bucks, I'm certain it's the fuel Level sensor. Now how do I figure out which level sensor I need?

    According to www.rockauto.com it depends on the VIN #.. My vin is xxxYU237xxx. Here's what rock auto says..

    "ACDELCO Part # SK1194 {#19121313} DUAL PRONG ATTACHMENT FEATURE
    SENSOR KIT,FUEL LVL 1ST DESIGN; VIN PRIOR TO YU145380, FOR 2ND DES SEE 25330713"

    Yay or nay?

    Also, 2 prong vs 1 prong?

    Looks like you need the same as mine according to your vin, sk1035. I was also unsure about the one prong or two and instead of pulling out I check and be sure, I just went ahead and ordered the sk1035 from eBay with free shipping for 59 bucks.

    Was your the one prong or 2 prong? How long did it take you to install?

    Lightbulb Re: Fuel gauge reading wrong.

    Welp, I have a 2000 Deville with 80K miles I purchased used about 5 months ago. The owner failed to tell me the fuel gauge didnt work so I ran out of gas a few blocks from home a few days later. After finding this forum and similar topics such as this, I finally got the courage to go ahead and replace the sensor. Bought just the sensor from Amazon.com (SK1035) and started the repair after logging 215 miles on a full tank.

    There are a lot of comments in these fuel sensor replacement threads where folks claim its easy and takes 20 minutes without the need of any special tools or any elaboration on the process. Even after asking the Autozone and O'Reilly auto parts guys if buying a special tool was a good idea, they said all I needed was a chisel/screwdriver and a mallet which is what I already had. Long story short, I wrestled with the retainer ring for about 1.5 hours using a screwdriver, a mallet, and some WD40. The ring wasnt rusted or anything, it was just locked in really really tight was not possible to get a good angle of attack with the screwdriver.

    After I got the ring off, I spent another 45 minutes trying to get the pump assembly out of the tank. This is because if you dont pull the module absolutely vertical, the pump assembly reservoir will not clear the tank opening. Even when I managed to get the pump assembly out, it was an extremely tight fit where I had to rotate it out of the tank hole like a screw, almost as if the pump reservoir circumference expanded a little after it was put in the first time.

    So after I replaced the level sensor which was pretty straight forward and re-installed the pump assembly, I could not get the retainer ring to fully lock. After damaging some of the plastic on one of the connectors on top of the fuel pump due to my efforts, I gave up with the ring halfway engaged and decided to order a tool to fully tighten the ring. Drove the car two days with the fuel level reading correctly with no issues. Also I should mention that the level sensor I bought was the exact same match for the one in the tank.

    I ordered the "Lisle 63000 Fuel Tank Lock Ring Tool" from Amazon for $28 bucks instead of the more expensive one the field manual specifies. The tool isnt made exactly for the 2000 Deville tank but it was the most cost effective option and I could tell that it would put pressure on the ring where it needed. The part was delivered and I fully engaged the retainer ring. The tool made working with the retainer ring a piece of cake.

    Hopefully this will help someone who is doing this repair and save them some time and frustration since I didnt see anything but "30 minute job" comments everywhere I looked, maybe my experience was the exception . Only if I was to do this again, then it would probably take only 30 minutes.

    Lastly, thanks to this forum and its resources, I was able to replace my passenger rear door window regulator....feels good having a chance to be a contributing member....

    Ha! Thank you!


    I ordered a new part. I recently received the wrong sku which was a 1030 instead of the 1035. Do I need to replace the retaining nut?

    No, just the o-ring between the pump module and tank. It should come with the level sensor.
