Revising my camping setup, took all my kit out of the rig and cleaned up the carpets. Found a cut in the carpeting. Curious if this is where the fuel pump is located. If yes curious if the pump was replaced by previous owners.

 

No, those are body to frame bolts.

Fuel pump cover is further back in the center of the cargo area. You need to lift the carpet to access.

 

+1, that's not the fuel pump. It lives here > Location Of Fuel Pump On Discovery Series II
