I've been thinking about the position of my vacuum gauges. Currently I have them just below the entrance hatch to the engine room so that they are immediately visible when opening the hatch. This is unlike their position when I bought the boat - in front of the engines which required descending into the engine room and peering around the ladder. I have considered moving them to the salon console. Two considerations--- are the length of the tubing, Racor recommend a max. of 15ft and I have already noticed that one of the gauges goes down to 5 psi and not lower when the engine is off. Secondly I am not sure that filters "suddenly" get plugged, seems more like a gradual build up process which would mean that the regular engine room "visits" ie: lifting the hatch would be quite sufficient to notice an increase in the reading. I usually switch over to the back up filters at 15. Ron Barr M/V Lady Brookhaven 42" Hatteras LRC New Bern NC

Ron: If you are using the Racor oil filled gauges they have a little rubber vent plug on top or on the back that you have to pull up slightly to equalize the pressure and that will let the gauge return to zero.
