You can't have almost no pressure. Other gauges are a little off. We don't know anything about the history so I am guessing that new fancy cluster and some senders have installation/compatability issues. Volts too high, water to low, oil at zero, don't know how much gas is in tank. Don't know if you were goimng 51 MPH when you took pic. Better not drive til oil pressure is fixed. You/we will need to go over the installation, one gauge at a time.
Who and when was cluster installed? Need full disclosure and history and your experience..... to begin with.
..so far you have not responded to any of your 3 posts.
