Maybe if you know the resistance of the VW sender..

but I did read the resistance in Ohms of a VW fuel sender recently..

I think it was 30 Ohms??

You would need to find out so that the gauge You order would work correctly.


Someone on here should be able to tell You..

Bug senders are 70ohm empty and 10ohm full so you would set it for the "Ford10" on that list.

That's the wrong sender though, you want the Bayonette fitting one for 71 onwards superbug not the screw in type for standard beetles.

If you take the gauge and sender to St George Instruments at Carlton [ask for Barry], he will set it up correctly.......and it work perfectly.
I'd rather wear a Beetle out by racing it than by polishing it!

Appreciate the advice!

Can anyone comment on the other gauges I mentioned? I assume they will be compatible...

The speedo will need a speed sensor of some description and you will need to fit the sender for the oil temp gauge somewhere.

Tacho will be fine but you will probably need to run a rectifier diode to clean the signal up abit, they're made for modern ECU generated tach signals so old VW points tend to make them abit jumpy.
