1990 Honda CRX Gauge Clusters

When I fill up the tank the needle doesn't move till about a day later and even then it doesnt move to the full sign. When I waste gas it drastically moves for ex. On day it'll be near full and a couple days later it'll just switch to below half, no slow movments just a sudden jump. Also The tachometer doesnt always work and when it does it either doesnt pass three or just jumps instead of smoothly increasing.
