According to this it is a know issue and the gauge has a reset procedure.

How do you reset the fuel gauge on a Chevy Suburban?

Press and hold the "Trip/Odo" button. Turn the ignition switch on and hold the "Trip/Odo" switch for about two seconds. Then, release the "Trip/Odo" button, press it again (do this three or four times), and finally hold it for about four to five seconds until the leveling information shows on the Odometer.Jun. 19, 2021

Go to Autozone.com navigate to "repair". Alldata has a section that desribes most R/R procedures for repair

No. The engine will still start, however if the sending unit is not working you will have no oil pressure and you will damage the motor and possibly lock it up. This vehicle can run with the unit not working correctly

I had the similar problem with my 99 suburban. I replaced the blower switch and works just fine.

the suburban engine compartrment allows for avery large V8s to be installed within its interior and yes any 454 will fit
