fuel gauge flickers

98 z-71 with 5.7 engine .my fuel gauge started acting funny. it flickers back and forth a little looks like a blur. had the fuel pump replaced two months ago, and now this just started .any thoughts?

ive been seein this issue on a lot of your body style for the gauge to be flickerin u either have a bad connection on one of your sending unit wires or possible the float arm might have gotten a lil bent when bein put into the tank and pushed it away from the contacts on the pump eitherway it should only be elctrical and your pump should be fine

The instrument clusters fail a lot and cause that. Using an analog voltmeter (won't show up on digital), check the signal wire coming from the sending unit. If the needle on that is steady, it's in the cluster.
