Second step to fuel line replacement (Removing the Fuel Tnk)

May 01, 2014, 07:32:58 pm

Park the motor home on concrete or blacktop so you can use a creeper to move about under the coach.  Also will be easier if it up on ramps.  You MUST use the safety bars to support the coach as the airbags deflate. 

Steps to Removing the Tank

      Drain the fuel tank
        •I used a drill pump and a 55 gallon drum to drain the tank.
 
.    Remove the door and hinge so tank can be slid out to get to the center connections.
      •Remove 4 bolts holding the swivel arms and remove the door.  This requires at least two people.
      •Remove the 4 bolts holding the hinge bracket and remove.  Also remove the two bolts below the hinge so the tank can
        be removed. 
      •Remove side molding.

.  Remove the fuel tank (VERY HARD)
      •   Mark and remove the electrical connections on the sending unit.
      •   Mark all 4 lines on the passenger side so they can be returned to their original position.  I used different color wire ties to
        do this.  Then remove the 4 hoses from the tank fittings and plug the ends. 
      •   Remove the 6 bolts holding in the tank.
      •   Lift up the passenger side of the tank and slide strips under the tank so the drain plug is above the hole and will not 
        hang up while being slid.
      •   Slide tank out. I could not believe the tank would not move.  It was soooo tight it would not budge even with two of
        us trying.  Tried pulling from drivers side without success and then passenger side.  I finally had to attach hooks to the
        bottom of the tank and use a small come along attached to the hitch of my truck and slowly ease it out. This must be
        done very very slowly as the center fittings will catch  on everything.  You can see where the tank was so tight it was
        rubbing on the sides. Sure hope it goes in easier.
      •   Remove center two hoses and plug lines
      •   Remove tank with my wagon and sit it aside.

Since Foretravel wanted to squeeze 192 gallons  in the U320 they created this small L in the tank to allow room for the hinge and left no space along the sides.  As time goes on the wall and tank adhere to each other which makes it so hard to remove.  The smaller tanks with a little space would be much easier to remove.

For owners of Unihomes, I did my 148 gal. by myself. No door removal. Removed bolts underneath and it pulled right out. Also reinstalled alone. Not heavy at all once the fuel is out.

Hi Jason,
  Nice work. Thanks for the documentation. Keep it up. Did the hole in the coach floor line up with the tank drain plug?
Thanks,
Raymond

The drain plug lined up with no problem.  The reason I pumped the tank instead of using the plug was for safety reasons.  I wasn't sure I could keep up with a bucket or would be more likely to take a diesel bath.
