I can remove the fuel pick up tube out a 863 and replace it then reinstall the new one in 30 minutes from opening the tool box ----- first time you do it , it is hard because you can't really see it , raise the cab and put a foam creeper or such over the steering bars and lay on it , reach behind the sunstrand pump on the right side the machine looking back towards the motor , feel for the 90 degree fitting , then use long pliers with the curved hooks on the end or a needle nose vise grip , grap the 90 and pull up , it's a little bit under the pump on the 863 , it ain't easy but once you get it , the next time will be a snap , try closing your eyes when doing it , good luck and where long sleeves when you do it
