That is exactly how I just installed mine. I bought a liquid-filled stainless gauge though, probably about $18 for the gauge alone.Bruce Sent from Samsung tablet. -------- Original message --------From: Josh Muckley via CnC-List <cnc-list@cnc-list.com> Date: 5/24/20 6:43 PM (GMT-05:00) To: C&C List <cnc-list@cnc-list.com> Cc: Josh Muckley <muckl...@gmail.com> Subject: Re: Stus-List Diesel Filter Regarding Joe's post: the official Racor vacuum gage is designed to fit the 500 series racor. The smaller one like I show in my video is no longer available new but was frequently installed on our era boats and is likely to still be on many of them. It is a 200 series. The 200 series has no provision for a t-handle (rather a band clamp) so the official t-gage won't fit. In my video I show having used a brass tee, 2 hose barbs, a street elbow, and an El cheapo vacuum gage which I believe I procured from Amazon. The total package was less than $20. The hose barbs allow it to be installed anywhere on the fuel hose connecting between the racor and the engine.Josh Muckley S/V Sea Hawk 1989 C&C 37+Solomons, MDOn Sun, May 24, 2020, 18:15 Joe Della Barba via CnC-List <cnc-list@cnc-list.com> wrote: A vacuum gauge is one of the best cost/benefit ratio improvements you can do. You can save a lot of $$$ in unneeded filter changes and get advanced warning when you do need to change one.

I therefore use a 10 micron, and use Biobar, as well as some Seafoam. I have some old crud in my tank, but where I can see it through the hole for the sender, the bits I can see are pretty well stuck to the bottom of the tank (and there are not many of them). That said, the boat had sat at the dock for +/- 6 years before I got her, and we have run 150 gallons or so of fuel through the boat in the last 4 years. I change my Racor every year, and I used to change the one on the engine every year as well. This time, I'm going to let the engine mounted one go another year. We still get a fine layer of black "grit" at the bottom of the racor over the year, but it does not appear to hinder the running of the engine. I'd rather swap out a $20 filter once a year than risk the engine shutting down as I go through a bridge opening with 3 kts. of current. To each their own, Bruce
