Installing racor vacuum gauges-gctid810424

[Happy_Friday]

I am about to install my gauges and I have chosen to connect them almost directly to the outlet ports on the top of the housings. My thinking was that although I would like to run vacuum lines to the helm and be able to check the vacuum pressure periodically from there, if I install them right at the filter housings then that will force me to do my checks from the aft stateroom "flip up shelf" and thereby make a more meaningful check of everything else while I am there. Does anyone have any experience with installing them right on the housing? The housings are not the newer T-bolt on the top types see attachment. Thanks

Mine are installed directly on the housings. I was of the mindset of how devastating a leak in that vacuum line would be while under way. Lose that integrity and you'll suck air immediately into the fuel path and lose your engines instantly. That's a single point of failure I don't need.

I use the ones with the tell tales, which to me are more valuable. They tell me the highest vacuum experienced and when it's time to start paying attention.

SomeSailor. Great point about the failure. That would be very hard diagnose and rectify. I also got the tell tail ones so that they would indicate the greatest vacuum during the latest use. I can't imagine why anyone would want another model of gauge.

I put them near the housing but not on the housing so that they do not get "bumped" or handled when changing the filters.

Vacuum gages also are a bit easier to read when filled with glycerin and using when using a "snubber" inline.

That allows the gage to read without chattering of fluttering of the needle.

The vac gages I bought were about $25 each / Stainless 2" face with a large sweep and 2% or less inaccuracy.

They are the only real way to know what is happening with your filters.
