It must be worth a mint. Hang onto it. Don't change a thing. Imagine the resale value when the polariser reaches its 50th birthday.

Does it have a fax machine in the glovebox?

This is a really good point from mikek that I'm now revisiting! I've learnt that if the holden fuel pump is dry, then it wont prime fuel.

Can an electric fuel pump be placed in line and activated only for priming fuel when required. Will the Holden pump pull fuel through it? Will this type of system work with any inline fuel pump or would it need to be a specific type?

Yes, a mechanical fuel pump will suck through an electric pump. Some electric pumps are designed to be mounted near the tank outlet and only "push" fuel up to the engine. Most of them will work either way, but unless you are buying a new pump, that old one may not. Also, you just need a transfer low pressure type, not a pump used for fuel injection systems.

I did this in another lifetime with an old flat head Ford V8 Mainline ute. The hardest part was finding a 6 volt pump! Just used an old type of push button starter switch to run it and prime the carby. That way it could not be left on accidently.

Fantastic, thanks very much for this. I think I'll setup the fuel system like that in this case. I guess having an additional electric pump will be good for when the mechanical one fails too.

I've just been reading about the Facet cube type pumps, it sounds like one of these pumps without a positive shut off valve will do the trick.

Thanks again.
