Hey Mark. There's only going to be 9" of space between the bed of your 2021 GMC Sierra 2500 and the bottom of the canister on the Pace Edwards Bedlocker Retractable item # PE78CV. The canister extends 10-1/4" out from the front of your bed towards your tailgate.
How tall is the fuel tank you're looking at installing?
