Re: Racor fuel vacuum guages
If one will be buying fuel from reliable sources (virtually all US supplies would be and local knowledge should keep you away from the bad ones), a water separating primary and engine secondary filter is probably all one needs. The alarms and gauges are never a bad idea, but not really necessary for a weekend warrior in the first world. I think the OP is in FL, but not sure of the boat's intended use.
Be sure the tank and lines begin clean, keep water out and properly dose all fuel with a biocide. Then inspect the clear bowl on the racor and change the filters regularly. If the filter starts to become excessively contaminated, you'll know something is up long in advance.
If your fuel source is questionable, that's a different story. If it is, I'd also want a by-pass filter, so I could keep the motor running, while it get somewhere to make the repair.
