TinkerMan)I already have a sender (originally for a fiat, has a hole to
bolt to something).
There is another thing that you need to know about your Fiat sender.
The VDO spark plug senders are thermo couples that generate a miniscule
amount of current that poweres the gauge.
The Fiat sender may be a sensor, not a sender and may require a powered
gauge.
I believe the Porsche sender I've got would work with a powered gauge and
the sender would go into some of the threaded ports that are on Vanagon
TypeIV heads.
I'd prefer it over the spark plug sender type VDO unit but haven't had
the inspiration to experiment with other gauges that I have in my tool
box.
I'm sure there is a simple solution to just mount it under a headbolt
since they are easy to get to on watercooled engines.
