excel fuel gauge

Post by andy brad »

Has anyone found the fault and fixed it on the VDO late excel fuel gauge so it remains steady when cornering.

I didn't know it was a fault?
Just no damping in the electrical reading?

Rgds, Curt

They all do that. It's not a fault as such.

There is an anti-slosh module you can fit. I have one on mine.

I tried a search for the link to the modification but couldn't find it.

Perhaps the mods will step-in to help?

That all sounds strange to me the fuel gauge never used to dance about when i first had the car so something is up somewhere . remember i have had this car from new and it was fine for years. So i cannot except they all do it they may when they are a few years old i shall investigate more. andy

There is a factory fitted anti slosh relay fitted - near the tank I believe. These do go faulty so you loose the damping. I don’t think these are still available, but the spiyda one will work, also allows you to calibrate your fuel gauge. My car has one of the early versions of this fitted.

All my VDO gauges (except the rev counter) are very fluttery - especially when I compare them to the rock solid Smiths gauges in my Esprit.

I've added a GPS HUD (driven from my phone) for when I drive longer journeys as I can never be 100% sure what my actual speed is.

Hi Andy,
Yes it is a wire wound 68 ohm resistor and would have a damping effect. Ensure the tank is well grounded and the float is not perforated.

Well this is the answer i got from my electronics guru inside the gauge is a resistor and if that fails the needle has no damping and will jump about i do not have picture hosting to post any pictures.on this site.
