Hi guys - I've got a '65 splitty in bits at the moment - the sender in the tank doesn't look as if it's ever been out - the van was running on 12v and the fuel gauge never worked even before I started the rebuild in - I've bought an aftermarket 12v gauge - my question is, will the old sender (possibly 6v) work or will I need to change it, if so for what? - it would be much easier now that the tank's on the floor.
thanks Colin.

Re: Fuel Gauge - sender
The bus uses a balance-coil type of gauge, odds are that the new one you have is thermal style - the senders are incompatible, you'll need to get a matching sender. Even within the same category, there's more to consider than the voltage...just what gauge did you get?

Re: Fuel Gauge - sender
Jim, thanks for my replies on both forums - I'm not actually sure of the make of my new gauge, as I'm recoperating after a knee op at the moment and the gauges are with the van, but........... it's one of a set of four (oil pressure/volts/oil temp) bought last year to hopefully improve the cab area/engine management - all I do know about it is that it's modern/new.
Hopefully I should get over to the workshop next week, if it turns out to be a thermal one (how would I know?), would you know which compatible sender would fit my Van without too much major surgery.
Thanks again, one good thing has already come out of this enquiry......... a link to your web site........ answers most of my other future questions - wish I'd read it earlier - Colin.

Re: Fuel Gauge - sender
Post the make/model of your gauge; if it's a popular brand there's possibly a VW-specific sender for it. Aftermarket gauges, if not made to be compatible with a specific OEM sender, could require a proprietary sender from the same manufacturer.
There may be a "universal" sender compatible with your gauge which you can adapt to the VW tank by making a plate to cover the stock sender hole.
For example, VDO makes one that can be set to read Full at 8Ω and Empty at 180Ω or vise-versa.
Pre`65 GM (and some trucks) GM use 0-30Ω
Later GM use 0-90Ω
Early Ford use 73-10Ω
Late Ford use 16-158Ω
Thermal VW use 73-10Ω (different than the Ford, though)
I can't take any credit for Speedy Jim's excellent site...it's a wealth of information for VW electrical info.
