Happy New Year,all.Advice,please. It seems the fuel tank sender unit intended for use with no voltage stabiliser are no longer available.I'm talking about the twist-fit type as opposed to the early bolt-in variety.How simple is it to fit an aftermarket 'stabiliser and could someone recommend one,please?Thanks very much.

The early sender unit for the non stabiliser car is the 6 screw/bolt in type, not the bayonet type, and are readily available from minispares.I recieved one from them a few weeks ago

Converting from non-regulaed to regulated is fairly straight forward.

As well as the later sender, and the regulator, you'll also need to change the gauge itself.

The Regulator terminals are marked 'B' that connects to +12V (via the key, your existing gauge will already have that wire there) and 'I' that connects to the gauge. The other terminal of the gauge then connects to your sender.

There was for a very brief period the early un-regulated type sender made with a bayonet type fitting.

Agree with Spider Chris there regarding a change-over. Your new fuel gauge won't match the other side if you are a concourse perfectionist

Also agree that during a brief period the non voltage stabilised sender units were bayonet types

Thanks to all three of you for your help.
