Fuel level bounce
I pretty sure most of our trucks do this but the fuel gauge bounces when you make turns and so on. is there a way to keep this from happing or is there a aftermarket sending unit for our tanks???

Re: Fuel level bounce
you could install baffels inside the tank to make less dramatic side to side fluid transfer inside the tank that would make the gauge somewhat more stabil

Re: Fuel level bounce
It's kinda funny to watch. Mine will vary by a whole 1/4 tank sometimes!

Re: Fuel level bounce
Maybe the float has lost buoyancy causing the fluctuation to be more dramatic???

Re: Fuel level bounce
What's the possibility that your sending unit has "worn" during its lifetime and the action of the float arm and the resistance "signal" that it sends to the guage isn't "spot on" accurate? It may well be that what you want to see just isn't possible with the aged components that you have. The newest of these trucks is 36 years old. How long do you expect to have an accurate reading?

Re: Fuel level bounce
Well the sending unit is less that 2 years old. Trust me I understand it will never be perfect but with all the differant accesories and upgrades etc.. Someone just might have a solution, or not.

Re: Fuel level bounce
This is a little off topic and kinda abstract, and no I haven't been smokin' that. I remember being annoyed by the fluctuating gas gauge and slosh of fuel in the tank, but now it'd be nice to see/hear since I haven't driven my GMC since June 2000.

Re: Fuel level bounce
When I floor the suburban, it'll drop by 1/4 tank.
The longhorn only does it when cornering. Is it THAT annoying? The clanking of the flaot in the tank is more annoying than anything. |

Re: Fuel level bounce
No it works so its not that annoying I was just wonder if they made aftermarket style senders to help reduce the amount of bounce, or are there any modifications. Trust me its not the end of the world just trying to educate myself alittle on this subject.
