Fuel Sender Access in 1997 41-foot Wide Body Pusher Detroit 60 Series - Mid Door

[isaltdusa]

My mechanic says that the cause of the fuel gage stuck past "F" is due to a bad
sender, not guage or ground fault. Therefore, he wants to replace the fuel
sender. So, have two problems that could use your experience and wisdom: 1) Is
it necessary to drop the fuel tank to access the sender? Mechanic predicts this
is s 10-12 hour R&R for the tank, expensive labor for what will probably be a
relatively inexpensive part. Is it possible to access the sender from inside the
coach going down thru the floor? Is there an access hole somewhere under my
carpeting I can use? 2) Where can we buy a new fuel level sender? Parliment in
Tampa is no help. Any other suggestions? Thanks!
