Ok out for some riding last weekend,
just some nice single track, a lap around hare scrambles course just playing around , not racing but a good pace. We're running through the woods great trail and we stop and get our bearings turn around and
pow instant immersion in a cloud of sweet smelling engine ice. 
WTF happened here take a look and see that the hose has blown off the inline temp sensor, which hooks up to a Voyager, ok clamp must have been loose . So I put the hose back on , tighten the clamp , friends donor camel backs fill the system and away we go. I get something to eat check the hoses again, Looks like it's moved so I retighten again, top up fuel and off we go . Get back from riding and load up bikes and here some hissing coming from mine again . I'll look at it at home I say . The next day I pull the tank and everything else to get where I want to be and I see that the same hose looks like it's moved 
again. I pull it apart and see that the temp sensor body is actually separated in the area between the nipple rib and center and deformed as in no longer the original shape as new the other end looks deformed also. Now before I bought this I questioned the manufacturer about the possibility of melting because of the material used to hold the sensor inline in the cooling system . I believe that it didn't melt but actually deformed and weakened . The ten thousand dollar question WHY . I had changed over to the high flow pump kit recently ,just as an up grade no issues with the stock one ,and put the stock tank back on to "thin the bike a little" for tighter woods work. I was stumped for an answer, 
then I looked at my cap ect. and chased the over flow hose .
here was the problem when I got forward on the seat/tank for tighter turns in trees, the tank pinched the overflow hose to the bottle, closing off the venting to the bottle. I believe I had found the culprit. If you change tanks be sure to double check clearances on all hoses ect. If I hadn't looked further into the problem the next time I'd go riding I would have had the same problem .
