Guage rattle is driving me nuts
I have an Isspro mech. FP guage. It is tapped at the VP44 inlet. I also have a needle valve inline to act as a snubber. FP guage used to act normal and rarely made noise. Now it makes noise all the time and has gotten past the point of being annoying. I have tried adjusting the needle valve with no luck. Anyone have any ideas? Would a second needle valve help?

I re-adjust mine usually when the weather starts getting warmer.
Just did it last week.
I shut the valve all the way down, the just crack the valve open until I get a reading, then shut the engine down to make sure the pressure bleeds off quickly.
Your attachment at the VP might need a short section of rubber line to act as a snubber.

I have occasional gauge noise even with grease gun hose and a needle valve.
Shovel is right- you need a tighter needle valve setting in warmer weather, as the viscosity of the fuel is less.

Moving hook up away from VP44 will help also. I used a "T" in the fuel line, about 18" aft of pump.

It was not a problem before. Only recently. And now with the needle valve completely closed, I still have rattle and a pressure reading.

Check all of your connections. I have found that the least little leak will cause rattle and needle jump. As a matter of fact, I just fixed mine again yesterday. The hose develops a minute leak where the hose connects to the gage. I need to replace the rubber with braided.

I bought the setup from Wildcat Diesel a few months before he closed down.

If you STILL see the pressure rise & fall with the valve closed off, then you've found your problem.....the needle valve is bad.

Any place that sells hydraulic/plumbing fittings should be able to come up with something.
1/8" npt should be the correct size.
Graingers sells them (but you probably don't have one of those there either, huh?)

I have the same Wildcat kit as you do. Mine does it on occasion also. Adjust the needle valve so it is barely open.
Pulling FP off the VP shrader valve does make it more prone to "buzzing". That was where my first connection used to be. Change it to pull FP off the bottom of the filter canister and used a grease gun hose as a snubber. Other than winter/wummer fuel changeover, you shouldn't have any buzz anymore.
