Filters For Vent Lines

[mikey_d05]

What are you all using for filters on your vent lines? I've been looking all over the place for K&N mini-filters but I can't find them anywhere. I have a couple of fuel/water seperators that would probably work but I'm not sure they would be very effective if flooded. I just re-did all of the vent lines today and ran them to the top of the firewall so I'm looking for something that's fairly effective but it doesn't have to be bulletproof.

Go to a Harley shop and get some breathers from them. They're not a standard HD part but people fit them when they remove the stock air box. They have a blingy cap on them but they are just a mini K&N filter all the same.

The same little vent filter is sold by the dune buggy vendors too.

I built a manifold for MISF's Scout where the vent side of the PCV system is routed thru it too. That way the engine, axles, trans, & t/c are all vented to the same place, inside the air filter. Potentially the PCV valve will pull a slight vacuum on everything.

Were we in someplace other than the coastal desert I'd be looking for some slight pressue so that the axles didn't draw in water when submerged.
