I recall seeing an article somewhere on how to rebuild the vac pumps on our trucks instead of spending a ridiculous sum of money at the dealer for a new vac pump. I think the rebuild used was about 20.00, but I'm not sure. Any help guys?

 

Genos garage sells a good kit

 

if the pump is broke you get a new one, if it leaks you get the seal kit from cummins or here http://www.scheiddiesel.com/display_part/2734.php
