Vacuum Gauge Rebuiler? in Avanti Pub Posted October 2 · Report reply Finale: one good directed spray with PB Blaster, then one with Gumout and it seemed to be working freely. After watching a You Tube video, learned you can make more of a vacuum like when sucking through a straw vs. inhaling. Stood in front of a mirror and found I could pull the dial all the way over! Put small amount of Sewing Machine oil on the movable points. Back in bezel and the dashboard tomorrow. Thanks for all your ideas!
