You're supposed to shim the pump stand to put the push rod at a particular height when it's at it's peak. This centers the stroke of the diaphram and maximizes its lifetime. The pump should already be set up to give the right pressure, because of the strength of its spring. -- Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ------------------------------------------------ To unsubscribe, E-mail to: <type3-off@vwtype3.org> For more help, see http://vwtype3.org/list/
