Where's it comin from?

[BDR]

My FP gauge is rattling. Not sure where it is comin from. I'm runnin a Isspro FP gauge, SS braided from the gauge to a needle valve, needle valve to a FP gauge tap right before the VP. The noise changes with engine rpms. Thinkin it might be the pulsations from the VP. Any ideas on what this noise is? Any help would be great.



Here's a link to my set-up:

yes it is pulsations from the vp. Some have put a schrader valve on the vp outlet and hooked the gauge to it to elminate the pulses. After the valve is on, you open it just enough to send the pressure through. The rest is dampened out.
