There's a pressure regulator valve of sorts in the cap. This valve is supposed to let air into the washer bottle ONLY if the spare tire pressure is above that which the spare might need. For squarebacks (red caps) that pressure is 36 psi, for the other models it is lower, something in the range of 28-33 psi, IIRC. When the caps get old, something happens inside them and this pressure sensing function fails, which allows you to drain your spare completely. > >little rubber sleeves...to keep them from leaking > > My hose is very solid and pliable, I don't think it was > used very much.

I've had several hoses burst on me over the years and in every case they looked perfectly fine everywhere except where the hole was. I think the hose can just be pulled off at each end, but there is an outer rubber sleeve on each end which adds a bit more pressure on the hose so it won't come off due to pressure alone. Save those rubber sleeves and reuse them. -- Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
