So I’ve read all sorts of forum threads about extending and raising the vent lines. Sounds like cheap insurance and a good thing to do. While I appreciate and enjoy reading about how many of you really push your Pioneers to their “submarine” limits… I, however, primarily do simple trail riding in mostly dry conditions, and may encounter at most a shallow stream / puddles or get caught in an unexpected summer thunderstorm.
So, my question is: how high do I really need to run the vent lines?
I prefer a hidden installation… I really don’t like seeing the vent line hoses running up the outside of the ROPS to the roof line attached with zip ties. Where possible, I’d like to run them inside the ROPS if possible.
So, for the gas and subtrans vent lines… wouldn’t running them up into the ROPS to the joint where the top half is bolted to the bottom half (about top of door level) be good enough? The joint is welded solid, so I don’t see how water could possibly get up there from deep puddles or high pressure washing… you’d really have to submerge the vehicle. So, my plan is to continue the vent lines within the frame, over to the ROPS, and up inside as high as the hoses will go. Thoughts?
Next… for the rear differential vent line… not really sure where to run that one, as the rear ROPS tubes don’t appear to have any entry points. Was thinking of drilling a hole to fit the hose, but worried that would compromise the ROPS strength? Other option would be to run the hose along the frame to the center passenger ROPS with the other two vents lines.
As for the front differential vent line, really not sure where to run that… maybe just up higher to some place under the dash?
For the clear vent line going to the electric fan… not sure if I even need to do anything with that one... appears to already be high enough and protected.
So, just curious what other riders, who don’t ride in such extreme conditions, have done? For just simple trail riding, shallow stream crossing / puddle splashing and perhaps the occasional monsoon thunderstorm downpour, how high is good enough?
thanks!
