Vacuflush issues???

[300 Ray]

First off I will start by saying I Have owned my 86 300we for 6 years now and have never had any vacuflush issues. This year after dewinterizing i noticed that now the vacuum pumpruns continuously as if a pressure switch isnt working. Hopefully someone out there has run into this. Thanx Dan

the switch is activated by vacuum. things to check
1: seal around the bowl. - put water in bowl if the level goes down without flushing the seal is bad or needs cleaning.
2: a vacuum lose from the bowl to the vacuum pump. check hose and fittings.
3: duck bills. found on either side of vacuum pump . clean or replace


that should do it

how do you access the duck bills do you have to remove vacuum pump??
