Question: Should I try to fix it???

DTC is for Low Fuel Level Sensor Input... I've removed the carpet in the trunk to reveal full access to the fuel sending unit (Its right there and very accesible). The dealership quoted a fix at $1300.00, but that seems a little stiff since everything seems to be so accesible. I have some experience removing and replacing complete engines in Chevy vehicles.... I was thinking about replacing the whole fuel sending unit but don't want to get in over my head.. What do you suggest?

Well if you have experience with working on cars, than this should not really be that hard for you to do.
First make sure that there is not fuel pressure in the fuel lines, this can be done removing the fuel pressure. Release the fuel tank pressure by removing the fuel filler cap. Also disconnect the battery ground cable.
Now disconnect the harness connector and the fuels feed line. Now remove the fuel filter, pump, and sending unit assembly. Replace all the needed parts and reassemble with everything it its original position.

If you have any questions about all this, I will be glad to help further.
Thank you for using DriverSide.

Car Brakes: How Do You Know When to Change Them?

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
