I bought a 0-15 fuel pressure gauge and am trying to decide the best way to hook it up for testing. After a search Danny said to use a temporary T but the link to the picture didn't work.  Is the T permanently mounted in the fuel line and then the npt fitting for the gauge just plugged when not testing with the gauge? Or is it better to just put a barbed fitting on the gauge and pull the fuel line at the T where the fuel line branches for the carbs and measure there? The barbed fittings are hard to get on and off. I don't want to mount the pressure gauge permanently.

thanks

A while back, Danny mentioned that the Harbor Freight vacuum gauge can also be used to check fuel pump pressure.  In fact, a lot of vacuum gauges sold for automotive work can do both and are pretty accurate.  This one is from Harbor Freight for around $16 bucks:

It is made by Westward (not Pittsburg Automotive) and is the same gauge that Grainger sells for $33 so shop around and don't spend more than $20 for one if it's for temporary use.  I bought my gauge back when I was building my '46 Hot Rod so it's probably 45 years old and still works great, for that once-every-ten-years that I get it out!

Remember to swap out the rubber hose for a new one every ten years or so.
