So I'm familiar with drying fuel as much as possible before putting it in the onboard tank as a preventative measure for keeping moisture out of the fuel system. But after some reading of past archival posts on the forums I've discovered that in humid environments ambient moisture as well as particulate contamination can enter fuel tanks through the tank vent.
So I've been researching fuel tank vent breathers + desiccants. I found several tank vent breathers out there that have the little desiccant balls that you must replace relatively often, but after some more stumbled digging upon this Donaldson part:
I'm in a very humid environment, am I just being overly cautious by worrying about this?
Has anyone tried one of these breathers on their tank vent?
Are there any other comparable parts out there that have been tried by the community?
Thanks for any constructive input.
◙ None of the above
No, it's a valid concern. I'm in a dry climate so I don't have the need for one.
Given that it's a Donaldson product I expect it will work exactly as claimed.
You may not need a drying element for your fuel tank, but dry environments do tend to be dusty. Have you thought about using a basic particulate filter like a crankcase filter breather on your tank vent?
That's the way Toyota designed the fuel tank vent; no change was needed.
