I'm sure Bosch had some kind of special tool squeeze it on and then > crimp the edge over in the 3 places. I have one which I tried to fix. The cap is plated steel and this one rusted thru. I took it off and worked it over with solder and then tried to crimp the cap back on. I THINK I was successful, but I haven't actually tried it. The one thing you have going for you is that there is zero pressure under that cap. I'm assuming that the valve & spring didn't get lost when your cap popped off. If the valve is gone, then the pump won't work right. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
