Hi..there..Sorry for delay seems system lagging a bit today?
Ok..i have checked through all the main parts catalogue for that sportage model over that year 05 -2010 /repair manual and as of yet cant seem to match exactly what the box is your refering too sadly..However if the tube as you say is rigid then It could most likly air intake related if the tube is of a larger diameter in size as appossed to smaller diameter pipe work etc..If you sure no fluid came out of that then i think that could well be what it is..since i cant really see it being the washer fluid tank as thats on the drivers side..Without actually seeing / trace that pipe section work back or get numbers from it - to maybe match it further then thats about all i can think it could be..if thats the case then the car should still be driveable in the mean time if its intake system related..
