RV Repair: Slow fueling, filler necks, bedroom wall

Question
I have a 2000 Tioga 29Z motorhome.  When I fuel the motorhome the pump constantly kicks off. I can't even put the pump on the lowest flow without it kicking off.  Is there something I can buy to help this problem?  The fueling for the vehicle is in the rear.  I have tried several different gas stations and they are all the same.

Answer
HI BRETT
BEEN THERE, DONE THAT
YOU'LL NEED TO SEE IF YOU CAN GET SOMEONE TO REROUTE THE FILL HOSE. THEY SCREWED UP A LOT OF THOSE. I'VE KNOW PEOPLE TO HAVE TO CARRY BLOCKS AND DRIVE ONE SIDE OF THE RIG UP ON THEM TO TILT IT ENOUGH TO FILL.THE HOSE PROBABLY HAS A BELLY IN IT, AND FUEL JUST WON'T PASS ANYMORE.
I HAVE EVEN INSTALLED NEW FILLER NECKS IN A NEW LOCATION TO SOLVE THE PROBLEM. BUT USUALLY THE FLOOR LINE IS IN THE WAY AND YOU CAN'T GO UP WITHOUT GOING INSIDE THE BEDROOM WALL.
MOST GOOD AUTO TECHS CAN FIX THAT WITH A LITTLE WORK.
