Bill, what I did to my AutoMeter liquid filled fuel pressure gage was to just leave the vent screw loose a few turns. It is located on the top of the gage, and is covered by the mounting cup, assuming you are using one. I just pulled the gage out of the cup, loosened the screw a few turns, and put the gage back into the cup. It`s been working fine for many years like that, no more troubles.
