Hey... I'm just saying... the pingle gets dirty... you just rinse it off/clean it.
Further, even if that fails... you can put it back together without the filter.
For the paper units... ebbs... just replace before. As you should go thru the bike anyway prior to the trip. Also, you could take a double sided nipple/coupler to bypass the paper unit.
And Ebbs... Drewpy calls me all the time for stuff. I can't say no and always help. Today, on my bday, I spent 2 hours helping my uncle install his mystery trike rear end on his bike. I stopped by to check it out and ended up bolting the whole unit on the bike... oh well...
