Tanks inc fuel sender

plumkrazee70 said
I have a tanks, inc tank with electric fuel.pump and drop in sender. My fuel gauge works fine (aftermarket guage) however if I get off level ground or make a hard turn the fuel guage moves dramatically and doesn't settle until I am back on near level ground.

I've seen floaties sending units. Does anyone have any luck with those? What are the fuel cell guys using?

I have a the same tank with aftermarket gauge. Mine is very stable. The only time I had an issue was when I first installed it and filled the tank with fuel, it didn't register as full. It didn't move until I drove the car a bit and it started working properly. I assume it was stuck in the down position.
