I had a similar problem with the pressure gauge on my old petrol engined rodeo - it was a loose connector where the wire hooks on to the sender on the motor. It was only being held on by the plastic cap. Took it off and pryed the connector out of its cap, crimped the connector a bit with pliers so it was a tight fit on the sender and then put the whole lot back together.
Mine also had the entertaining habit of dropping back to zero whenever you backed off the throttle.

Might be a guage problem but do not run it till this is verified. If you have 0psi at 4000rpm engine life is measured in milliseconds not seconds
Sanding your knuckles before starting work can help. That way you cant skin them
