2014 Escalade. So of course my wife just filled up on gas 10 minutes before she got home and the fuel pump died. (Original with 175,000)

What a headache, gave up trying to get the fuel out. No fuel pump relay, it's controlled by the module. You can't siphon out of the fuel supply line through the existing pump. And if you remove the filler tube hose, there's something blocking it so you can't do that either. Anyone see one of these in their tank? It's like a built-in rollover valve. And when I tip the tank back, it's airtight.... No fuel sloshed out.

So for anyone interested, it wasn't that bad lowering the tank full of fuel, using an inexpensive harbor freight transmission jack with a piece of plywood protecting the underside of the tank. Once removed, and strap down to the jack, raise it up about 2 ft, remove the pump and siphon to 5 gallon jugs on the floor.

I recall over the past couple years postings about people having issues, taking 20 minutes to fuel the vehicle. Makes me wonder about this check valve or rollover valve that was never referenced? Kind of wondering if removing it would have some sort of negative consequence on the function of the entire fuel system.

No rust, but this is Oregon. That's not wet from fuel around it, I was starting to clean off the coating of dust and dirt.

That trans jack paid for itself right there. Make sure you verify your evap charcoal canister isn’t losing its pellets and install a new one before the tank goes back in.

Another way the f/p goes bad is having the carbon pellets migrate into the fuel system. If that hasn’t happened, you got lucky & missed the short straw. Interesting that GM calls out a different part # for the base & ESV

Quick question for ya if you’re still working on the truck. R/A lists a physical flex fuel sensor for the 14 Esky. Do you see one on the fuel lines under the truck.

I’m thinking it’s an error and R/A forgot that Esky were still Gen 3 in 14 but the pick ups had moved on to Gen 4 in 2014.
