odonnebj,

"If it ain't broke, don't fix it" Ever hear this expression?

If you do not have any fuel starvation problems, the filters are OK and do not have to be replaced. Just carry spares with you and if you notice a loss of power on a long hill, replace the primary (inline) filter just because it is easier and costs less. If you still notice the power loss, replace the secondary (can) filter. Unless you get dirty fuel, you probably won't need to replace the fuel filters you are using now for thousands of miles. New filters don't filter any better than used filters.

If you get a dirty load of fuel like I did in CO on RT76, (first station from CO-NB state line), the new filters will plug almost as fast as the old ones. Lucky I had spares because I had to replace 3 filters in all because of the dirt in the fuel.
