My 02 has nothing there and I haven’t heard of that. Why would there be a screen there?
One of my previous UKON-TAHOE had the same obstruction in the filler, after some sleuthing I found out it was there to prevent fuel theft, so much for siphoning, my 2014 does not have that obstruction.IIRC my '04 had a (removable, I think,) screen right where the fill tube connected to the tank, so if yours has that a siphon hose won't get farther in. But you can still get quite a bit of gas out using the siphon method.
That's how I do it, I use a paperclipLocate fuel pump relay in fuseblock. Remove relay and place a jumper between terminals 30 & 87. Do not stick anything down in the relay socket that is thicker than the relay pins or you may damage the fuseblock.

It’s not a high volume pump, it’s gonna take a long time. Also keep in mind that fuel is actually used to cool the pump and it’s possible you will damage it by running it until it’s empty. It’s always been advised to not run your tank empty because it will destroy your fuel pump, plus you’ll be sucking all the crap at the bottom of your tank through. Think this through. Do you really want to take all day running your fuel pump and probably ruin it, or stick a length of old garden hose in it and siphon it out in minutes.
Huh. I figured if it takes all day to burn through a tank of gas with the engine running it would take all day to pump it out too but then I’ve never tried it. It was super easy for me to siphon it in minutes. And I’ve heard it’s bad to run your tank empty but maybe that’s not true? I don’t let mine get below about 1/4 but mainly because I’m supercharged although on my Silverado I did run it empty once and it worked fine afterwards. I found out when that truck says empty it’s empty. That’s a fuel cell though and I had to cut the pump down to fit the height of the cell so the level sender is off. That truck also never sees under 1/4 tank.Not taking sides, but there are some facts to consider:
The pump is designed to stay submerged inside its own bucket regardless of the fuel level in the tank. I don't know what it's called, but through that whole mess on the assembly, suction created by the pump sucks the fuel from the tank through the bottom of an outside bucket then it's dumped into the inside bucket that the pump is inside of. This inside bucket stays filled and the pump pulls from that to feed the engine. Also, they pull from the bottom, so it's already "sucking all the crap at the bottom", anyway. these pump run for hours and hours on end while people sit idling, creeping in traffic, on road trips, etc. They're rated at something like 150 or 190 LPH (I don't recall exactly), which is 40-50 gallon per hour. Based on these numbers, if you were pumping down a full tank, you'd have it done in about half an hour. But, I'm sure that doesn't account for the restriction of the fuel lines, etc. So, lets just double it. I'm sure the pump has an hour's run time left in it.
You could set it up and find something else to do, just keep an eye on it to shut it down as soon as it starts sputtering. It'd be nothing different than if you were running the engine for an hour or however long it takes. Might wanna keep a battery charger on the battery, though.
Every motorcycle rider that has ever had a reserve position on their petcock keeps this rattling around somewhere in the back of their head...plus you’ll be sucking all the crap at the bottom of your tank through.
