First off, no water was found in the water/fuel separator. That's good.
Second, I watched the breather and depending on how we're steering, it definitely has a little risk of splashes. For sure risk if we swamped the rear with an abrupt stop.
So, since I really don't have the time right now to re-route the breather line elsewhere, I went to the auto parts store and bought a 90 degree hose and have it zip-tied onto the breather outlet with the cap at the top. Basically, it's my "Surf Snorkel".
The hose is attached to the outlet with black zip ties. The cap is likewise attached with black zip ties and the hood on the cap is kept at the right level by a few rounds of gorilla tape on the hose.
A little ghetto engineering, but this will totally do until I find a more asthetically pleasing solution.
I tried to buy some threaded 90 degree elbows and such, but the thread on this fitting was SAE and all the plumbing stuff I could find didn't match up. Actually the hose looks cleaner than a bunch of pipe fittings would have anyway--AND it's flexible, so if someone bonks it, there's some forgiveness and play.
