Good that you figured it out. The description on the Bosch wasn't very clear, but the pic looked like the other aux pumps.

Agreed I just did the fuel pump in my 2008 Yukon XL Denali (1500) and it was a Bosch from the factory.
At least that is what I think. I replaced with AC Delco though like this. ACDelco MU1653 GM Original Equipment Fuel Pump and Level Sensor Module with Seal https://www.amazon.com/dp/B001S30GXY/ref=cm_sw_r_cp_api_i_pAl8EbFKSFJ0B
o8 burb 2500 , just replaced pump cause of rust , had it smoke tested because a p0442 code. pump still worked but started to leak fuel when filled up . yes has Aux tank also. had to replace the plastic lines that connect tank to vents aux pump and charcoal canister because line was stuck to fuel pump line and came apart (broke). other than waiting for parts not that hard to replace pump.
Got it done in a couple hours yesterday with breaks for dinner and a little league game. Turns out someone had been in there before, pulled out an Airtex pump dated 2013. So in effect the Airtex lasted longer than OEM... and it still works just doesn't keep up at high rpm anymore.
Good to know though because the only one I could get when I needed it was another Airtex.
Only PITA was the stupid evap hose that goes over the crossmember.
