RE: Vaccume gages and filters

The vacuum gage on my FL120 read at about 5 or 6 when my engine would shut down. That was on my maiden delivery voyage (and if you think 12 elements are enough for a 500 mile trip, not always).

Since I replaced the lift pump and changed from 2 micron filters to multistage I have never seen over 1. One gage (on the 30 micron Racor) reads 0, one gage reads close to 1 (on the 10 micron Racor) when new.
