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.
