Although ESM are generally seen as trustworthy (I've got no complaints about their service but there's been some disgruntled rumblings recently on facebook about their Customer Support), the fact is that Hardi do not make a pump with as low a delivery pressure as the SU. Their lowest pressure pump is almost twice the pressure of the SU.The Scotmoose wrote: ↑Thu May 02, 2024 7:26 am Hi there folks. I had minor problem with fuel pump (sticky points) and have considered that at Monty's age (56) I might just change the fuel pump complete and have looked at SU vs Hardi on the ESM website (I trust ESM and am sure they will be selling the correct Hardi pump to suit the pressure needs of the Morris Minor). Financially, the Hardi is less than half price of the SU (I am negative earth these days - apologies to purists - Negative earth SU pump approx £25 even more expensive than positive earth one!), which has immediately has made me worry about the quality of the Hardi pumps. The SU certainly looks a more robust item. I then saw the full repair kit and wondered about restoring my SU - is it so very difficult? Then just to throw a spanner in the works there is an electronic conversion kit, which would take away the points side of things. I notice there are no repair kits for the Hardi, which would seem to make it a throw away item. Although, like everyone else, I have to mind the pennies, I am inclined to think that if I have any further problems, the easiest option will be to just go the whole hog and get a new SU pump, not for originality, but for dependabilty.
Like any other business, ESM are seeking to sell to customers; Hardi market the pump as suitable, ESM aren't going to question it.
Yes there are SU electronic ones which do away with the points; my personal view is that if the electronic one fails, a tap on the top to free a sticky set of points isn't going to get it working. Therefore I prefer the traditional arrangement.
The overhaul kit is quite easy to use and there are videos on youtube of people overhauling the SU.
The simple fact is that the SU fuel pump is probably the most ignored item on the car. People work on engines, gearboxes, all manner of items, but few think to check the points on their fuel pump or even check the inbuilt filter, until it starts misbehaving.
The SU is an excellent bit of kit, it just needs a little bit of love every so often....
