Boost Gauge Defective??

Hey everyone. I think i either have a vaccuum leak, or my gauge is defective. Pease watch the video and you will see what i am talking about. I just reconnected and resealed all electrical and boost connections with electrical tape.

NOTE: listen close at the start of the video, you will hear this weird rattling/ electricity noise. I am almost certain it is coming from the boost gauge. It has been doing it more and more.

It's a mech gauge, seems like the fitting on the back of the gauge may be loose or you did not use plumbers tape when you installed the threaded brass fitting? I assume by hitting it, you are shaking the vac seal loose, i guess. not sure from the vid what exactly it is.
Gauge may just be broken too.

there was no brass fitting. i think the gauge could be broken.. i dont see how though. but for some reason, the gauge started reading the vaccuum correct now. maybe its because i re connected all of the connections? any other ideas? im gunna contact NSP and ask for a new one.

fuckin NSP. i thought they were supposed to be sooo great. well i sent them an email. anyways, it stopped getting caught, and now falls to 23hg. i know it should be beteen nineteen and twenty one but is this a possible vaccuum pressure? or should i just replace the gauge.?

I love my Electronic Omori gauge, i sold my NSP gauge and went electronic to get away from mech gauge Buzz.

I would replace yours, or hope they have a good warranty and replace it for you.
