How can I dampen a fuel gauge?

Hi Tom,
Thet are two differents ways to solve your problem:
- a mechanical solution (as experimented by Perry)
- an electronic solution (as indicated here below)
(I don't consider the replacement by an other system as a reel solution to this problem)
About the mechanical solution, you can fix a small shock absorber in the flotting sender inside your fuel tank to hold the float movement or to provide a separated float casing (as a tranquillization chamber) with a very small communication hole (to the tank) to minimize the fuel flow between the float casing and the main tank and consequently, the float movement. However, we have to admet that it is not easy to do it.
Fortunately, the electronic solution is by far more easy (and very cheap): you have to install a small chemical condenser (try first with a 10 microfarad 24V that you can find in the electronic spare part shop) between the fuel gauge sender input (positive side) and the ground (negative side) and observe the result (remove your fuel gauge sender and shake it by hand in medium position) . If there is not significant improvement, try with a 100 microfarad value (alway 24V). The condenser is working like a spring and will absorbe (and restitute) all fast variation signals. Let us know your result. Good luck.
