I am in the process of installing a new fuel tank due to rust in the old tank...the tank is HUGE ! (Maybe 40 gallons)...I emptied the tank, jack under tank, loosened the front straps and am having a problem with the fill hose...cannot get it loose from the pipe coming from fuel door. Is there a thread for installing a new tank in the squarebody Suburbans. Impossible to loosen the rear strap bolts as the bumper and class 2 hitch are blocking access. I pulled the tank in my 90 GMC Suburban R20 to replace fuel pump and it was a breeze ! This one is a nightmare ! Do I dare cut the rubber fill hose and replace it with the new tank ?
