SU Fuel Pump or Hardi replacement?
Posted: Fri Aug 18, 2023 10:36 am
Hi Gang
I have a new Hardi 13312 fuel pump that came with the car and having looked it up on eBay, it states a compatible use with a number of Austin and MG engines but not for the 948cc Minor.
Ordinarily I would dismiss the part as incompatible but I do wonder that if it works for the 997cc Mini Cooper, surely it would do for my car, wouldn't it?

I also have what looks like the original SU pump (part No. 4080) and wonder whether it makes more sense to simply clean up and recondition this one for originality? Or are they generally considered unreliable?
The closest looking model I can find on the SU website is AUA66 but I don't see the small (what looks like) a vacuum nipple on it in their photo (which are all rubbish and don't show a complete unit at all). The EPK700 repair kit seems to be for all AUA66 models so if that is what I have, I'll get one.
At the risk of ridicule, why is a dual polarity pump cheaper than positive or negative unit? If you can use it for both polarities, why would anyone buy a positive or negative only pump?
