The piping on my Polaris consists of hoses over bulb type fittings at the various components and then there is a nut on the hose that is usually too small to actually fit over the bulb. You basically screw the nut as tight as possible, but it won't actually go up and over where the hose wraps the bulb fitting. It's been like this from day 1 and I used to assume it's jsut the way it was supposed to be. Now, I get frustrated with the hoses coming apart. There has to be a better way. So, how is all this supposed to be connected? I can post pics tonight if it will help.
