Bouncy Fuel Gauge

What is normal for our rigs? How much should the needle bounce?

I have a 1972 K5 and recently replaced the original cluster with a restored cluster. After taking the rig out for a test drive after replacing the cluster I noticed the gas gauge bounces a lot. I have to be honest, I don't drive the rig much since buying it so I don't remember what it was like with the original gas gauge.

How much bouncing needle is normal from sloshing gas in the tank? Mine will bounce and when coming to a stop at a red light, it will not stop bouncing before the light turns green again. This seems excessive to me.

Tbone1964 is helping me and we would like your input.

Thanks !

Re: Bouncy Fuel Gauge

I don't think it is really a question of how long it bounces but how much.

Mine will move a little bit, but not much. I think these trucks had slow moving gas gauges, you might just have one now that moves a lot faster.

Also, how much does it bounce? Around 1/4 of the gauge?

Re: Bouncy Fuel Gauge

Mine doesn't bounce much. The slider and float go Up And down slow so that doesn't happen. Or isn't supposed to happen.

My fuel gauge doesn't work at all. It's on my short list of things to get done this year.

Re: Bouncy Fuel Gauge

I had a gas gauge do that once and it turned out to be something wrong with the gauge. I took it out and just by shaking the gauge the needle would move. The needle is supposed to have a little bit of resistance in it, but this one you could blow on and make the needle move. Changed it out and never had a problem again.
