dave, yes i havr replaced the fuel filler hose on my 2005 landyacht. i needed to replace mine because it was cracked and old due to south florida climate, plus it was rubbing on part of the frame. it was not overly difficult if you are somewhat mechanically inclined. to access the hose, you must go thru the last storage door which is under the fuel filler port. on mine, this was the dump station area. i actually cut part of the aluminum cover away in order to access the area needed. in retrospect, i should have drilled out the existing rivets and then replaced them upon completion. there is about 4"-5" of clearance between the holding tank and the floor of the rv to work in. the fuel filler port is metal and it extended down to where i could access the clamp that held the hose to the pipe. the hose then extends horizontally towards the center of rv where it then turned downwards to attach to another metal pipe that crossed thru/over the framed work of the rv. i had to replace this approximate 24" section. i used rated flexible fuel hose to do this. it is a very tight squeeze and i tore up my knuckles in the process (i have since learned to use mechanics gloves). it was tedious loosening and then tightening the clamps, but it was doable. do not try to acess thru floor of coach. i looked closely at this option and it spelled real trouble. i made this change 5 years ago and have not had any difficulty or fuel spillage since fixing it. i hope that this helps.
