Squeaking Sound Coming from 225 /6

I just finished the install and tested it. It measured 50 psi after crank and stayed there for several minutes as I let it idle and warm up. Here is a video of what’s it sounded like in the engine bay.

Any help is appreciated! Thank you all for the information so far.

Gauge was way more responsive with no air bubble in it you could see it vibrating when bled solid. With a little air pocket, it was more stable. The bubbles were just bugging me, watching it change size when revving it seemed unnatural for a hydraulic gauge.

Your best bet is to get back on track and install a mechanical oil pressure gauge to help diagnose your oil pressure issue. Do a temporary install.

I like the plastic/nylon lines. Just route them away from sharp edges and heat and they last forever.
