I realize not everyone would desire to go this direction, but it is an option for some who do not mind doing the hard work. After testing for voltage at the fuel pump and even applying external power to it, I knew I had a faulty fuel pump. My coach would not start at my rural location. So it was either have it towed from my property to a repair station or figure out a way to get to, test and replace the pump. Others may have done this, but this is how I managed to avoid significant expense. I used my Dremel metal cutting saw to remove the metal flooring in my lower storage compartment immediately above my fuel pump location. Although it was a tight fit, (6' 1" and 210 pounds) I was able to access the fuel pump and test it. Finding it faulty I was able to remove the pump from the fuel tank. Then I found a new replacement pump on ebay for $315. Local retailers wanted $550 and up. I replaced the fuel pump and had a friend turn on the ignition. When I heard the pump whine I knew I had it licked. I then went to Lowe's, bought a sheet of 2X3 sheet metal installing it in the hole I had cut out in pieces. I pulled and glued the felt carpeting back over the new sheet metal and it looks good as new. I figure I saved myself $400 easy. Now I can access the fuel pump easily for any future failures. But just so you know.....it can be done.
