Answer 2

i looked up a fuel filter for a 6.0 lieter fleetwood and foud out
that the fuel filter is in the fuel pump. to change it you unscrew
the metal bowl under the fuel pump and the filter is right there
for this application. you didn't give a model or an engine size so i had to guess at what you had but i hope that this helps

Answer 3

should be in back of the gas tank.
