Thanks for the replies

I thought I needed just a positive downward flow to the hose. I did not see anything on the end of mine like a one way thing but will look on the floor of the garage as my old hose broke apart when I took it out and I had to just poke the end through the floorboard and I have not found it yet.

I ended up using a more ridged hose that I had that was for joining two water (rain) barrels it was more ridged so I heated one end and it ended up forming around the nipple and looks like it should hold nicely. I will have to heat it up or cut it off when the time comes to replace it. I just put it thought the grommet in the floorboard and it had about 3 inches that went past the floor of the car I hope that this work I can't see why it would not unless something melts the end.
