Question about 2001 GMC Sierra 2500HD
I think on that year the quick connects are built in to fuel lines. If they are the only thing that will work are these quick disconnect tools made by OTC. They can be found at just about any parts store.
The guys I work with break the nipples off the sending unit with the lines attached and then remove the broken parts after the tank is lowered. I have never had a problem getting the lines to release with the tools listed above.
Once the tank is out there will be a metal retainer ring holding the sending unit in the tank. tapping at it with a hammer and small pry bar, punch, or screwdriver is all you need to get the retainer to rotate and come off.
