Fuel filters . Have extras on board . I presume your later model has primary and secondary spin on filters ? Likely a Racor type fuel water separator as well .
If you change fuel lines you could lose prime , have fuel and a garden sprayer (or other means of pumping fuel into the system ). Change filters one at a time. Fill new filter with fuel , have it ready . Run engine for a few minutes, shut down and change filter . Re start , let engine smooth out , shut down and change other filter .
You can slice old filters radially just above the mounting boss to get a look at the filtering material .
That will give you an idea of your fuel condition.
If coach has been in use and running well you might consider getting it home before performing preventive maintenance.
When I bought the '86 it had done a 1300 mile trip , so I took a chance and drove the 600 miles home . Ran fine .
Good luck!
